I remember this place from when I was a kid in the fifties and I don't know if there were 14 of them or not, but there were several rental teepees there.
According to my friend Rick Balda, his uncle painted the original designs on the Tee Pee. Rick's father was from Ecuador but I don't know if he was referring to his Mom's brother or his father's brother. It would be nice to verify the original painter of the Tee Pee structure.
