He's put together a complete set of Beta. And every single card is signed by the artist.
There are 302 cards. There are 25 individual artists. Sure, if you can find Dan Frazier, Anson Maddocks, and Doug Shuler all in one place and in a good mood, you can probably knock off all 98 cards in a shot. But what about Fay Jones, the artist for Stasis?
Anyway, Markus has very kindly sent along some pictures of the collection. Look upon his works, ye mighty, and despair. And then click any section to zoom in.
