Imagine programing a truck to know what house to stop at
Cool. My Dad was in 11th grade when these adverts were done.
He told me the ice man's vehicle in downtown Detroit was drawn by horses when he was a kid.
, and the horses knew which homes had ice service; and which did not.
ie the ice man would walk on the sidewalk to catch up to the waiting ice wagon that was already at the next house.
As so as iceman removed the ice block with the tongs and he commanded the OK signal, the horses would go to the next house, 2 ,3 , away. The ice man would them carry the block to the inside of the customer #1's house's ice box; then walk to the next house where the ice wagon was already there.
In an early 1920's book on designing a homes electrical loads, it has the cost as 10 cents per kilowatt hour. Thus with the rate of inflation, this is like at 10 times todays prices. A refrigerator in 1928 was a rich mans device. Few could really afford to pay the electricity to run one; if the fridge was free.
My mom's notebook of 1940 shows a monthly bill for the ice man of 4.50 dollars
