Before the current West Penn Recreation Center was built in 1929-30, this small building on 30th Street served as the recreation center.  Although the Historic Pittsburgh Image Archive lists the same date, January 25, 1922, for both these images, that seems doubtful, because the little building is gone in this photo:

The nearest building on the left is the Lyceum, which was located at Brereton and 30th Street, where the church parking lot is now.  The views were taken from different angles — but not that different — look at the upper right corner of each — those distant building are similar in each.
