YMCA & Central School, Bisbee, AZ, 1920s? Albertype

YMCA and Central School, Bisbee, AZ -- Marked the Albertype Co. Brooklyn, NY - Divided back. Unused. T us a very light stain right above the chimney at the top of the picture. Upper left corner is bumped. But all in all, pretty nice shape.

Not sure how to date this card. My best guess is 1920s.
