The character is posed dramatically, revealing his disfigured face and holding his (removable) mask aloft. He is apparently standing at the summit of a dungeon of some sort, as there is a miserable-looking person wailing behind a barred window at his feet; a rat also scurries by.
In 1969 Aurora reissued this kit with glow-in-the-dark pieces - specifically, the head, hands, and mask. Owners had the option of building the model with all normal black pieces, or substituting the glow pieces for certain ones. The box for this issue measured 12"x12" (shown at right).
