RE:The Year is 1920Fuel for cars was sold in drug stores only. Sorry, gas stations existed from the early 1900s. The Old Motor 1916 Photo of a gas station, gas price 26 cents a gallon (equiv 10.80 today!): Not included in post, house price 1920 maybe 4,000 dollars, even after the big inflation after the war of 15-20%.
For any prices of 1920s, multiply by about 40. Ex: eggs, 14c/doz equiv to $5.60/doz today.
