These signs were painted by Bob Middleton approx. 1975.
Bob still has the original layout for this job. (Click for image.) The layout shows a telephone number beginning WA5, but the photo above has the number as 925-7800. Bob's memory is that "the Ezra Cohen phone number was changed after I painted it... [It] must have been painted by that sign shop after 1975 ???? Looks like Concord Outdoor work."
There was another Ezra Cohen sign on Allen St. at Broome St., but
this was not a Mack sign.
