6" across and about 3.5" tall. According to Tom Felt, it has been seen in "black, green, and amber (all colors both glossy or satin finish) and can [be dated] to the late 1920s, since it appears in a 1929 Thayer & Chandler catalog (a firm that sold blanks for home decorators). It looks like it ought to be New Martinsville, but no proof has been found to date."
