Small Movie Poster/Card Find; The Good, The Bad, The Ugly

I just got a unit on Thursday with these little movie poster/cards in them.

Posteritati Movie Posters-www.posteritati.com
They are all for The Good, The Bad, The Ugly and all the different countries movie posters for the movie but are really small. I have searched online for a while and can only find info on the actual posters, which are from 250$ to 1,800$. Im sure these are nowhere near that, but hoping they still have some value. They are all from 1965 to 1966. 

Anyone have any suggestions as to how to find out or who I could contact?

Thanks
