Just got back from the flea market. I got some tiny 7-up bottles, maybe a couple inches tall. There was a six pack that only had three of them. I thought $12 was too high a price, but I went and got them anyway because I've never seen them before. Since they are too small to have anything stamped on the back, I was wondering when they were made. I also wonder where the other three bottles are. Maybe someone drank them?
