ACEO stands for "Art Cards, Editions and Originals". ACEO's have one rule - they are 3.5 inches by 2.5 inches - the size of a trading card. They can be made out of anything (clay, wood, pen, ink) as long as they meet the one main rule of size. This is an original handdrawn and cut, stamped with archival, inked and painted with watercolor pencils. The bird on the limb is a raised separate piece attached to the card. There are little gem flowers on the end of the branch. This sketch card will not be reproduced. The card comes signed and dated on the back of the card. There is also be a list of materials used to create this card on the back. The card measures 2 1/2" x 3 1/2" and fits in standard card sleeves/protectors. The card is on 140lb, cold press, watercolor paper. I ship all art cards in hard plastic premium top loader card holders and then wrap cardboard around the card holder. They are shipped in a bubble padded envelope to help prevent any damage during shipping.
