As we get closer to the Flatstock book becoming a reality we have been going through the API archives to see what Flatstock posters we have. While some Flatstocks contain large sets some are pretty thin.
Flatstocks we know are slim include 1, 5, 6, 7, 11, 13, 14, 15, 16, 17, 18 and 19. Although seeing what you have for any Flatstock would be good to cross reference what we already have.
Also if you are attending Flatstock 20 the sooner you get your poster designed the better.
If you have done Flatstock posters or have any please contact Geoff and let him know what ones you have. An e-mail just listing which Flatstock and which artist is great.
e-mail Geoff at email@example.com or ou can post stuff in this thread too if that's easy enough for you.
It would be greatly appreciated if you post them in the Flatstock Gallery under each respective Flatstock to.
