I picked these up a few weeks ago at an estate sale. I actually picked up a giant stack of post cards for not much. These were definitely ones that stood out. These Ripley Believe It or Not post cards are from the New York City Odditorium in Times Square. I can remember being a kid watching Ripley’s Believe It Or Not with Jack Palance. That, was a great show!
My guess is that they are from the 60’s or maybe a bit earlier since the entrance fee was only 50 cents. To my surprise, the Odditorium is still in New York City, Times Square. I think I might need to make a trip soon! http://www.ripleysnewyork.com/index.cfm
