GTP of Art

An iPhone game about the art market

Guess the Price of Art

A Klimt, a Hokusai print, a Toulouse-Lautrec poster. Each one sold at auction or privately, and the figure is on public record. How close can you get?

The collection

Real works, real prices, properly credited

417public-domain artworks

7departments, from Old Masters to Posters
$1K–$450Mrange of prices, sold 1885–2025

Old Masters, 19th Century, Impressionist & Modern, Asian Art, Prints & Multiples, Posters and Photographs. Images come from museum open-access programmes (The Met, the Art Institute of Chicago, the Cleveland Museum of Art, the Rijksmuseum) and Wikimedia Commons. Every price in the app names its sale year, the venue, whether it includes the buyer's premium, and the published source it was taken from. Tap the info button on any reveal to see all of it.

Prices are approximate public figures for historical sales. Most auction prices include the buyer's premium; private-sale prices are as reported. Nothing in the app is an appraisal or investment advice, and a past price says nothing about what a work would fetch today. The app is for fun and learning. Some classical works include artistic nudity.

Built for everyone

Quiet, honest, accessible

No timers, no real money, no betting. Dynamic Type up to the largest accessibility sizes, VoiceOver labels on every work, a button alternative for every gesture, and respect for Reduce Motion and Reduce Transparency. Everything is bundled with the app, so it works on a plane and in a basement gallery.

Why the name? GTP stands for Guess The Price. Say it out loud and you will hear where the wink is.
