I grew up in Brooklyn, NY. in the 40's. There was a merry-go-round that sat on the bed of a truck that came around. There was also a whip that came too but not as often. They cost pennies to ride, not sure how many, and we loved it.
And now that you got me started... There also were men from different countries, Italy, Mexico, Spain, etc., that would stroll the streets playing guitars, violins, etc., in hopes of you giving them a few pennies. There was also one man I'll never forget. He carried on his back an old stone grindstone about 14"-16" in diameter that was foot operated. All the ladies would listen for his call and he would sharpen siccors, knives and just about anything else you needed done. In the summer there was a hispanic man that would push a woooden wagon that had a big block of ice and he would shave the ice for you and add different flavors to the ice. And my next door neighbor, Joe Garguilo, had a horse and wagon and would sell fresh fruit and veggies everyday. Brooklyn where I grew up, had steep hills and all these folks would walk up and down hoping to make a few pennies to feed their families. Now you just ride to the welfare office. But I guess for hungry kids, that is progress.
