This nice little buffalo thimble is from a place called English's Buffalo Farm in Bainbridge, Indiana. Their "Trading Post" is the only website I've seen where one can order both thimbles (they have four different choices, all $4.95 + S/H) and buffalo tongue. The website has a huge catalog of souvenirs and other stuff (no spoons!) and buffalo meat recipes. I'm curious about the Bison Kabobs.
I think one can go visit the place: the website has a map.
