An ACEO is a miniature work of art meant for trading and/or collecting. The size is always 2 1⁄2 by 3 1⁄2 inches (64 mm × 89 mm). ACEOs are a wonderful and affordable way to collect your favorite artists' work. This ACEO is a funky Westie. I used an outlining archival ink pen as well as Copic Marker and liquid acrylic in a shimmering gold. The paper is slightly cream or off white. This artwork comes matted in a bright white 5 x 7 mat for presentation and its protection. The ACEO can be easily removed. Artist's signature is located on the back. Your new original ACEO will arrive to you packaged nicely in a clear sleeve and sandwiched between two pieces of cardboard to ensure safe arrival.
