I've had a big stack of these Dino stickers (don't stick anymore) for many years. Just wondering where they would have been used?

I'm guessing these are from the Sinclair display at the 1964 - 1965 New York World's Fair.

Correct. New York World's Fair. They also made the green Dino banks there too.

Thanks guys. I sort of figured that they might have been from some big event.
