This is from an old edition of Wild, page 27 of Issue 25, Winter 1987. The cartoon is apparently by Ian Gunn (Biography here), and has always amused me. I'm not sure of the origin of the word play, maybe Ian Gunn thought it up. It is said that it was first seen in an outdoor shop during a sale. It was used in "The Red Green Show" too, but maybe they saw it in an outdoor shop, as this cartoon predates the show. Ian Gunn's interpretation of it into pictures is priceless.
