Scott, Very nice collection of cabinet photos...I zeroed in on the Mexican one from the San Diego area...I don't recall ever seeing an antique photo of a Mexican baseball team....If anyone has any from the El Paso/Juarez area or any from Chihuahua Mexico please post.

I like to take close-in shots of vintage photos with a digital camera, then it's easier to see the background...see the 6th photo down in the link above of a c1890 12 3/8" wide x 6 1/2" tall panoramic photo of Hobart College and University of Vermont...which I took at the 2009 National...
