Recently, I was reading a biography of Charles Schulz (of Peanuts fame). In an early chapter, the book mentioned that Mr. Schulz, as a boy, sent an item to Ripley’s Believe It Or Not about his dog, and that it was published on February 22, 1937.
The Toronto Daily Star ran Ripley’s Believe It Or Not as a regular feature, and I found it:
As the biography explains, “Sparky” was Mr. Schulz’s childhood nickname. I might be imagining things, but I think the dog looks a bit like Snoopy.
