Another banner week for Then and Now readers. Paul G was the first to correctly identify last week's image as Yarnall's stationary store. Below, via our friend's at the Historical Society of the Phoenixville Area, is the full explanation.
Yarnall’s stationary store was located at 20 South Main Street. The business was run by Karl Yarnall for 20years until his death in 1961. At that time it was sold to become Croft’s stationary. Most recently 20 South Mainwas the customer service center for Comcast. The retail space in the building is now vacant.
