Hi Mary B,
The old bar at the southwest corner of Mission and Ajo was the Mission Club.? There was also a Tojo's Bar next to it in later years, after the Mission Club went defunct, perhaps same owners.? The picture with the horses was taken inside the Mission Club and a copy of the photo is in Opha Probasco's book:
I recall my grandmother telling that the Mission Club was owned by the Probasco family, but Opha probably describes the origins in his book.? It's a good read, describing a great deal of what life was like along S. Mission Road and the surrounding area in the 30's thru 50's.
Interesting that the a copy of the photo ended up out at the Ryan Field eatery...
Hope this helps.? Happy New Year!
