There is a whole world of miniature glass out there - some of it was made as a toy (doll's houses) and some of it was made as trade samples so the salesman would not have to trundle the full weight around, and some of it was just made as gadgets, like the Bimini items. And then there's souvenirs, of course...
I predict that in a few years' time someone will come along and write a book on glass minis. Maybe it is you?
