I’ve been looking for dioramas depicting mining operations that were popular at 19th century World’s Fairs as part of my World’s Fair research. I came across an organization that sponsors a “Logging and Mining Modeler’s Convention” which has a contest for model railroad, logging operations, and diorama construction. Just another way that miniatures are popular. They have been doing this for 28 years. Alas, it is in California but check out their web info here:
