As I've written in today's paper, the artist Keith Tyson is offering 5,000 Guardian readers the opportunity to own a free downloadable artwork by him.
The costs you'll have to bear are those of printing out the work on A3 photographic paper – and framing, if you so choose.
Here's how you claim your Keith Tyson History Paintings print.
From midday today, Tuesday December 9, visit this link.
Once there, go to the Explore section and follow the instructions. You will be asked to enter your geographical location – which forms part of the unique title of each print.
Downloads are limited to one per IP address. The work will be available to the first 5,000 readers to download the work.
