I got these cool Physics flash cards at Vintage Voltage this year. Vintage Voltage is a must-do you’re into old radios, records, Tesla coils, or robots.
Anyhow, on to the flash cards. The cards are made by the Vis-Ed company in Ohio and they are still in business! The set I have now costs $14.95, but my set is better because the cards have that great old book smell. I’m not sure how old the set is, but the company address doesn’t include a zip code, just a postal zone (Dayton 8, Ohio!). So the cards were made after 1943, but before 1963.
They start off with the basics.
