The mark consists of a rectangular field of light color, containing three horizontal lines, sectioning the field into unequal segments. The first horizontal line appears at the top of the rectangular field and has no material above it. The full body profiles of two men are depicted below that line. The man to the left is facing upward, dressed in dark clothing, and wearing a hat. The man on the right is facing downward and appears bald, wearing light, dotted clothing. Both men are sitting on saddles. A second horizontal line appears below the men, with the literal element "PUZZLE OF THE TRICK MULES." below in block letters. Below the text appears a design element of dark-colored mule with an open mouth, facing to the right, with a light colored segment in the middle. The third horizontal line appears near the center of the rectangular field and below the first mule. Below the third line is a second mule, facing to the right, with a closed mouth and the same coloring as the first. Below the second mule is the small image of a hand with the index-finger extended. The finger is pointing at the literal element "CUT THE CARD ON THE LINES (INTO THREE PIECES ONLY) AND LAY THEM SO THAT EACH MULE HAS A CORRECT RIDER.".
