Let's talk about the art, shall we? This art is based on a promotional still that we saw in the Color Glos post here. But the art here, shall we say, is a little odd. I'm pretty sure this art was done in house at Welcom, or at least in England. It very much resembles the art found in an English book which I hope to post in the not too distant future.
As with the black box puzzles, the box is fully illustrated on all sides although the long sides have the same illustration, one would assume that these characters adorn other puzzles in the series.
