Help with Mexican (?) Cuban (?) Cabinet Photo's
 

I just picked these cabinet photos up and I am looking for suggestions as to year and place. There is no writing or notations on the back of the frames or the photo. My though is probably 1900-1920 at the latest. The M could be for Mexico but also the name of a athletic club.


Sorry about the rotation of the images. Leon if you can rotate them it would be great. They appear on the board rotated from how they look when I preview them ??
