Altemus Filmascope Reel

Every now and then I find an Altemus item that I just have no feel for. Below is a reel of film filmed by the James C. Muir and Company, a Philadelphia firm. This reel contains 32 pictures (no text) from the Wee Folks Cinderella Series Tom Thumb Book (http://henryaltemus.com/series/series188.htm).

The reel is titled “Filmascope” Tom Thumb and was “reproduced with the Permission of Henry Altemus Company Philadelphia”, Copyright 1921.

Apparently Muir produced a number of these little reels in the late 1920’s.

I presume that the little metal canister is an original. If anyone has any information about this little reel, I would appreciate hearing from you.
