I Collect Yellowstone Park spoons and other like Montana related spoons. This one here is 4.5" Yellowstone Park spoon that is extremely thing and looks like it could be a rainbow trout at the end of a fishing pole with the bowl being decorated with Yellowstone Park. I have searched patterns and common souvenir makers for the national park but I can not find a single maker that matches. I know Joseph Mayer & Bros made some souvenir spoons depicting fish but not like these.

Anyone have any idea who might have made this?
