Happy April Fool's Day!
Here are some vintage pranks and jokes from my collection.
Rear View Mirror Mailable Joke Box, 1947
This little box is the size of a postcard, with a depth of about half an inch. The front advertises its contents as a "rear view mirror", while the back has space for an address and postage stamp:
these could actually be mailed.
The joke is apparent once the box is opened:
There were hundreds of different mailable joke boxes like this one available in the 1940s and 50s, when they were all the rage for a time. This one was made by H. Fishlove & Co. of Chicago, a novelty company founded in 1914 which was one of the most creative of the joke box manufacturers.
The Shine Gallery has a large selection of old-store-stock joke boxes for sale, but sadly, I don't think you can mail them anymore...
Bang Gun, 1940s
