Can't figure it out. I say 20s or 30s, my girlfriend says its the 50s or 60s
Based on the automobiles I would say the 20s/30s.
I'm almost insulted by the idea that this is the 50's or 60's, as a former resident of SLC. Utah is backwards but not THAT backwards.
It'd have to be between the 1880s - when the first street cars were used - and the 1920's, judging by the automobiles. Here is a nice picture of Main Street in 1890, and another from 1912.
