March 31st, 1938, and January 6th, 1950:
Why hire help when you can have kids? In the cartoon on the left, Het tells us that it's those dirty farmers who put their own children to work rather than paying strangers. But twelve years later, she's admitting that she uses her own adult children for the same purpose.
Isn't it weird to see the term "birth control" in A. a comic strip and B. 1938?
