I have my own collection going on and prefer to buy only originals. However, I have mistakenly purchased prints from time to time. Click here for an interesting discussion of originals vs. copies by two creators of ATCs. I create and sell my own as well, but, sadly, I haven't yet found any artists willing to trade them with me. I love the idea of artists trading little miniature paintings with each other. Many of the artists on Etsy, including myself, who create ACEOs belong to a group called the "ACEO Etsy Street Team." Browse this wonderful blog for links to many miniature works of art.
I was pleased to find a two-page spread in the 2010-2011 Dick Blick Studio catalog featuring ATC supplies for artists. Log onto www.dickblick.com or call them at 800-828-4548 for your very own copy of this BIG catalog of art supplies. Happy Creating!!!
