That kind of work was a good gig, if you could create a travel circuit that worked for you.
One day, a guy showed up with Ice Cream. Just happened to be perfect time and place - whole neighborhood bought and kept buying.
Another guy, Potato Chips. This fellow drove out in an arc around the fringes of his contemporaries’ travels. Just happened to be the right place, at the right time. Really big cans of potato chips.
Maybe 1 tinsmith in the mid-1950’s. Milkman (milk, butter, eggs into the mid-1960’s). Diapers (booming business; and then nothing, circa 1959 - “thanks to” Proctor * Gamble). And of course, the Fuller Brush Man (really good brushes, not “Made in Japan”).
