Here is a photo of the AR Demonstration Room in Grand Central Station in New York around 1970. It was there for years with various AR speakers and electronics and the turntable.
It was only for demonstrations, not for sales. It was permanent for a few years in the late 1960s/early 1970s. Does anyone remember this?
(This was a frame from a youtube video at 2:33 by Trainluvr called 1969 plan photos about NYC.)
