In the 2nd postcard you can see the Ely Theater

There are 3 shorter buildings to the left of the theater, and the Miners Club is the center building, of the three

The theater building is also in the top postcard. To me, it looks like the Owl Club in the top postcard matches the location of the Miners Club in the bottom postcard. Yes??

According to the chipguide, the Owl Club was at 444 Aultman Street.

The bottom postcard is in our collection, and may be used on the chipguide. I don't think the top postcard is ours, so please don't use it.
