The same images were also used for a series of calendars in the 1950s. I think they're very cool and nostalgic.

There's 15 different images used and the calendars were available in 2 sizes.
I've managed to pick up a number of them. It's easy to imagine these hanging up in a workshop or garage in the 1950s.
