The 1st image is a postcard found in The Vanished Spendor (Vol I), written and assembled by Jim Edwards and Mitchell Oliphant (Abalache Book Shop Publishing Co, Okc, 1982). The entrance (bottom) faces East to Broadway. Today, entry is from either Broadway or Park Avenue.
The 2nd is a photo taken in 1925. At left, South of the building is the Egbert Hotel (originally the Bassett Building built around 1905) and, furthest South, the 1890 Post Office but no longer used as such. North of the building, the 5 story (darker) Wright Building (originally the 1902 India Temple) and the further away Southwestern Bell Telephone (light) buildings are in the farground. At right, the edges of the Skirvin and Insurance Buildings are seen.
