This ad was a reminder to some adults of the 1950s to recall childhood.
It skips over a key point. Before people could have refrigerators, utility lines had to be installed to houses.
Very often the utility company bought advertising to expand the franchise as you can see from this 1907 ad.
Gas stoves and electric refrigerators were part of the second wave of consumption after their original first utility use as lighting.
Good advertising can sell a product so if you have one contact the Tribune and stop carrying around 50 pound blocks of ice.
