Highly collectible, ACEO's are Art Cards Editions and Originals - a specialty born by artists on Ebay years ago. Since that time they have gained in popularity. By collecting ACEO's you have a small "gallery" of works from various artists at a very small price. Frame them, put them in albums or mobiles. Some even slip them into pouches with magnets on the back. Whatever way you choose to display them they are just a delight.
