Western Electric News, March 1925, pages 35-37. Article by E. D, Hall. Covers the evolution of the New York City exchange system from manual to Panel switching. The main traffic diagram and the last two photos were quarter page size in the original publication. Scanned at high resolution and enlarged to full page - but the original coarse half-tone screen used in the photos limits the quality that can be gained.
