ACEO stand's for ART CARDS EDITIONS and ORIGINALS which are traded and sold through various ways. They must be 2 1/2" X 3 1/2" to be an ACEO. The one's here were painting in Germany. These may all be bought as a signed print for $8.00 each. Purchase through Paypal under artwithlove@sbcglobal.net To let me know which one, count to the one you want. Sorry, that's the best I can do at the moment.
