This has been floating around Facebook with the question “Do you remember when gas prices were this low?”
If you’re immediately thinking “1950s,” you’re just a little too early. This sign can’t be from any earlier than 1961, when Gulf decided to drop its super-premium Gulfcrest (from a purple pump!) and replace it with the sub-regular Gulftane.
Why would they do a thing like that? Presumably to compete with the cheap gas from that questionable-looking station on the wrong side of the tracks.
