I did some research and found that this image has been sold on eBay as an 8x10 by someone who claims to have acquired most of the originals of Reginald McMahon, who took this picture and who has done extensive writing and photographing of the area for the Bergen County Historical Society in the 70s. I've posted a lot of his photos on the BCHS board.
The seller has given two different dates in his auctions: 1972 and Nov. 1974. Given Homer's information, Nov. 1974 would seem to be the more accurate date and Two Guys appears to be open when he took the picture.
