These photographs require a bit of detective work. The original is not labeled as to place and date. However, the autos in the photo date it to the 1920's. A search of the newspaper database comes up with Max Haber operating a shoe shop at 15 East State Street, so I am going to make a leap of faith and surmise that this pristine R.C. Maxwell photo shows the store fronts along East State street from number 15 on the extreme left. Don't miss Karl Weidel's establishment, and be sure to examine the exquisite architecture as you pan to the roof tops of the buildings in the photo.
I'm going to go along with your assuption, since the "Arcade Billiards/Bowling alleys is where I worked as a kid in the 40's setting pins for two cents a game.
The term "Arcade" came from the Arched passageway noted in the photo that had shops, and led to steps that took you down to the Front St. Entrance. Travers book store was in the vicinity of the Weidel building who in later years moved around the corner to South Warren St. just below the First Mechanics bank building at State and Warren.
Great photos, and another great job.
