With that this should be taken into consideration. Things seem to be much cheaper back then but consider what wages were. Considering that, things are about the same. The average wage in 1912 was $500/$700 a year. Then there was world war one and wages spiked to an average of $5000 a year in 1928 (the year of the post card ) All and all, prices are about the same percentage of a pay check. The model T was worth more in 1928 than what it cost new in 1912 but still pretty low.
