Too late for Valentine’s Day, but this card was found in a nifty shop here. This place has typewriters for rent, and while I was buying this card the clerk was instructing a young woman on how a manual typewriter works. I found this amusing, and astounding, that one would need to be instructed on how to use such a simple and familiar machine. Conclusion: I obviously have no idea of how uncommon a manual typewriter is to some people. Perhaps this person would also be unfamiliar with a rotary dial telephone? Don’t laugh! I can’t milk a cow, can you?

Although I grew up in a coal town I can milk a cow and a few other things. How about using a crank telephone? Victola? Crystal set?
I love the card!
The very concept of a carriage return is mysterious to many new typewriter users. The whole thing simply is unfamiliar to them. It’s fun to watch!
