ACEO (Art Cards, Editions and Originals) is a group of artists selling mini art, baseball card sized (2.5" x 3.5" is the required size), some original, some prints. To find great these great art trading cards on ebay, type ACEO into your search. Great to collect and trade and gift! They fit into the baseball card sheets, so you could make your own individual, one of a kind coffee table book. Or I see that if you search under aceo, you will also see great hand made books to keep and display the trading cards in. Or you could frame a collection of them in one large frame. Anyway, just some ideas for these little gems by all kinds of different artists!
