What can I say here? The gag was as old as the hills, even in 1967, and the newsprint color registration was horrendous, but this is an archive of my cartoons and, what the heck, “we all have to start somewhere”.
By the way, thirty years later I sold another version of this gag, with just four sales charts up on the wall. Which charts did I eliminate, and which did I change? You'll just have to wait and see.
