Piggly Wiggly: parking lot in 1950 Kroger: 1950s storefront and parking lot Winn-Dixie: Lovett's storefront in 1951
It is very hard to guess what make/year the white car is....but defiantly mid to late 50's. Here is a picture of a 1956 Oldsmobile Super 88 Sports Coupe for comparison.
I'm guessing 1957 Oldsmobile super 88 4 door Hard to tell in that pic with faded colors but probably white on the bottom and sunset glow on the top.
I think I posted on another thread, but comic Ron White said a 90 year old German/Texan farmer showed him a plow with a seat and said he though that when he saw one, he believed everything that could be invented, now had been.
1958 Olds I remember them as having that look where you see the "Eighty Eight" in the picture plus the stripes on the rear fender.
