The screen credit for ABC staff artist Hy Bley appears in the form of a scribbled signature on the closing credits, among many other scribbled signatures like "Abraham Lincoln" and "A. Goldfish". Bley was possibly the artist who prepared the show's cartoon graphics revealing the guests' names.
When the show first began there were only three people on the panel and the top prize was $75. The panelists who ran out of questions or didn't make the correct guess paid the contestant a check for $25. However, in 1954, the panel expanded to the more familiar four person set up that was used on "What's My Line" and "I've Got a Secret" and the top prize went up to $80 and each panelist who didn't make a correct guess or ran out of questions now paid $20.
