A specimen card, a luggage tag, a ledger page, a letter, a wax seal — fourteen different objects that look like they came out of the same forgotten institution. Same hand. Same paper. Same catalogue numbering. Built in about an hour, in a chat window you already pay for.
The Brantwood Insect Cabinet — one of the eight invented sources, on the kind of desk it was meant for.

Chapter one · the problem
Ask any image model for "vintage Victorian botanical ephemera" and you get something lovely. Ask it fourteen times and you get fourteen lovely things that have nothing to do with each other — a different hand, a different paper, a different century, numbers that mean nothing at all.
Buyers cannot always name what is wrong. They just do not believe it, and they scroll on.
A real archive is not a style. It is a place, a person and a filing system — and it shows up on every single piece.
Chapter two · the mechanism
Three moves. Everything in this system is one of them.

Eight sections that define an invented institution once — who kept it, where, the hand, the paper, the palette, the catalogue prefix, the emblem, the drawing style. Pasted once at the top of a chat, every object after it inherits the lot without you repeating a word.

A ledger page is packed. A luggage tag is nearly empty. Most sets fail because every piece carries the same weight of text. Each of the fourteen objects here has its own density, so a tag reads like a tag and a ledger reads like a ledger.

Nothing in a real archive was made in one sitting. A correction slip glued at its top edge decades later, in a colder ink. An office stamp three degrees off square. Room left empty for the next correction. This is the part nobody else does.
Watch the emblem
This is Atropos — the death's-head hawkmoth of the Brantwood Insect Cabinet. Every piece below is real output, and the moth is on all of them: pressed into wax, screwed to a drawer, printed on a ticket. That recurrence is the whole trick, and it is what a single prompt can never do.






Chapter three · the proof
The pin is there. The plate number, the collector, the date, the remarks — all there, in a careful hand. Where the moth should be there is a pale outline where the paper stayed unfaded, four rust-ringed pin holes, and four fragments of wing.
Nothing on it is a ghost or a mourning device. It is a record that outlived its subject, which is what half the paper in any real archive is.
A market prompt has no vocabulary for a record of loss.
The moth on this page is Atropos — the one missing from that card.
One specimen, fourteen objects
One source, one foxglove, one afternoon. Every piece below ships inside Provenance as a finished worked example. Tap any of them.















Eight sources ship with it
A fen botanical society. A dispensing chemist. A travelling circus. An insect cabinet. An observatory. A seed merchant. A subscription library. A Christmas household.
Each with its own custodian, handwriting, paper, catalogue prefix and twenty-five specimens — and the handbook shows you how to build a ninth of your own.
The eight, in their own words








Eight labels, eight catalogue prefixes, eight sets of motifs — and every one of them numbers its own drawer. Nothing here is shared but the method.
A shop's worth, from one system
Forty-five pieces, drawn from all fifteen worked folios in the Vault — every institution, every object type. Hover to stop the rows.
You do not write these prompts
One HTML file. Opens in your browser, offline, forever. No account with us, no install, no subscription.
Pick a source, an object and a specimen from three menus. The Desk assembles the rules, the Provenance Block and the object template for you.
Press Copy, paste into a chat. The first prompt carries everything; every prompt after it is short, because the chat already knows the institution.
Switch to Folio run. It steps you through all fourteen objects in order, remembers which you have made, and hands you the file name for each one.
Beside every prompt it shows the Check the result list — what must be true of the image before you use it. That is how you judge output instead of hoping.
Off the screen




Printed, trimmed, held, glued in. Tap any of them to see it full size.
Output runs about 1024 × 1536 pixels — 3.4 × 5.1 inches at a true 300 DPI. Superb at tag and card sizes, above 400 DPI at trading-card size. Provenance ships ready-made A4 gang sheets so a whole folio prints on one page at true size.
And it tells you plainly what these are not: not full-page background papers. Nothing in the product pretends otherwise.

Before you ask
You need a chat account that can generate images — the one most people already have. Nothing else. No software to install, no account with us, no server, no monthly anything. The Desk is an HTML file that runs in your browser with the internet switched off.
Yes. Digital kits, printed kits, finished journals, physical products you post — all of it, no credit required. What you may not do is resell Provenance itself, or sell resale rights to it.
Yes, and it says so everywhere. Provenance is a prompt system: it writes the instructions, your chat generates the images. The bonus also covers how to disclose AI-generated work in a listing properly, because that is now part of selling this kind of product.
About 1024 × 1536 pixels — 3.4 × 5.1 inches at a true 300 DPI. Ideal for tags, cards, slips, tickets and labels; above 400 DPI at 2.5 × 3.5in. They are not full-page papers, and the product says so plainly rather than letting you find out at the printer.
Eight sources ship with the system, so a buyer who uses them straight shares those institutions with other buyers. That is why chapter eight of the handbook and a full format reference are included: they show you how to build a ninth source of your own — your own institution, custodian and catalogue prefix — which nobody else has.
You pick three menu items and press Copy. The difficulty is not the prompt, it is judging the result, and the Desk puts the checklist next to every prompt for exactly that reason.
Thirty days, no questions asked.
Then another, and another, until your shop is full of things that look like they belong together — because they do.
