ACEOs, sometimes called Art Cards, are collectable, tiny works of art. They can be matted and framed to hang on the wall, or displayed in an ACEO collection. An ACEO is always two and one-half inches by three and one-half inches. That is the size of a standard sports trading card. The rule about size is the ONLY rule in the ACEO world. An ACEO can be created in any medium the artist desires - watercolor, acrylic, oil, colored pencils, ink etc. Some may even be found made from wood, clay, fabric, and metal.
Many people display their ACEO collections in the same kind of plastic sheets and albums that sports card collectors use. Small plastic envelopes (or sleeves) are available to fit them exactly.
Some owners like to slip an ACEO into a greeting card as an extra surprise for a birthday, anniversary, or holiday wish on Halloween, Christmas, or Easter.
ACEOs have a full range in price as does any art, from pennies to hundreds of dollars.
