Today's picture was taken in 1940, and it shows a blacksmith shop. This would have been a time that was pretty much the end of the era for blacksmiths. It is amazing to think about how much things have changed since the days of the blacksmith. Consider the blacksmith shop . . . a blacksmith would shoe horses, fix broken things, and fabricate things. Almost 100% of anything spent in the blacksmith shop would stay in the local community. The blacksmith would no doubt need helpers, so he gainfully employed people in the community. He would probably also hire young people as helpers, and then they would learn the trade through apprenticeship. Almost everything used to operate that way, not almost nothing does.
