![Keystone Movie Operator Set](http://www.collectingkeystone.com/wp-content/uploads/2022/08/Keystone-Movie-Operator-Set-1008x1024.jpg)
These set as a whole are rare. There is the operator pinback button, the paper badge that it came on, a group of tickets and the remains of a paper arm band. I also have a better condition set shown separately.
From my private collection.
