Which artist designs cartoon posters with hundreds of characters?

Richard Scarry?

Where’s Wally or Waldo?

I’m afraid not. They were a little more adult in nature. Nothing too raunchy, just a bit of comic nudity here and there. The poster I remember best was a running track with a myriad of events happening all at once. There was also a winter olympic one. Cartoon style was quite balloonish – big noses, big hands.

The artist is Jan Van Haasteren. His artwork is typically printed for use on jigsaw puzzles. Here is a print of the Track and Field/Olympics you are talking about.

Scott C. does that sort of thing occasionally. But your dentist would have to be awfully cool to have some of his art hanging up.

@rpm_pseud0name I love Van Haasteren’s puzzles. Interesting to know his creations may also be in poster form.
@Rheto_Ric Are any of the suggestions what you were looking for?
