Yes, they were made by Frito-Lay and were on the market from 1969 to around 1971. They came in two flavors that I remember, Galloping Green Onion and Buckboard Pizza. I tired of them after a few bags, they had far too much flavoring on them. Seems to me they were shaped like a scallop shell, more or less. It was around this time that the original taco-flavored Doritos came on the market and I got hooked on them.
