Ripley's Believe It or Not! 50th Anniversary Edition #[nn]

In 1968, instead of publishing a regular annual numbered volume of Ripley's Believe It or Not! (Pocket Books, 1941 Series), Pocket Books published a special anniversary edition for the strip's 50th anniversary.

Later printings (including this one) dropped "50th" from the title.
