I own a building in the small town of Jefferson, SC, and we have this old picture of the town that everybody cherishes... I wish I had a higher resolution scan but this is from a postcard... if you click it it should get larger. Anyways, this picture is always listed as being from 1925, but I have reason to believe it's from earlier than that. I own a building built in 1920, that's not in this photo, so either me or the photo date is wrong

The reason I post it here is, because I believe these to be a bunch of Model T's parked in front of the buildings and thought since I have little knowledge of the early vehicles before the 50's or so, maybe you fine folks could date or identify some of the cars? It's my understanding that it's hard to give a specific date of a Model T because they were made similarly for many years, but perhaps whatever that second car in the picture with the strange wheels could give away the date? There was a cotton market just south of this intersection (the truck in the middle of the road is leaving with a huge haul of cotton) and as I understand it there were some fairly wealthy people that owned the businesses on this street, however everybody around were farmers. My point being perhaps some of the cars were very new and owned by the money people in town, or maybe one or two of them are expensive enough to be a giveaway to the date?
I guess what I'm asking is... do you see anything in this photo that is definitely after 1919? My building is the two story building on the left in the background, I believe it was built in January of 1920.
One interesting thing I saw is on the right in front of the second building appears to be a gas pump, but if it is it's awful tall! I know that particular building was the post office at the time, so maybe something else was hung outside of early post offices?
Any help is appreciated, I also posted a picture of how the same scene looked this morning, May 5th, 2019.... perhaps 100 years later!
