If anyone is interested, I found this on E-Bay This rare Real Photo postcard is of the "Polski Store", owned by A. Piotrowski in Trenton, NJ. Mr. Piotrowski poses proudly, smoking a cigar in front of his storefront windows, which feature calendars, floral arrangements, a miniature house, Murad Cigarette (and other) signs, a small banner with a cross on it, and a sign reading "Park Floral Co, Broad St. Park, Orders Taken Here". Research in Trenton City Directories shows that Alexander Piotrowski owned the Polski Store at 534 North Clinton Avenue in Trenton. The number "534' is on the transom in the photograph, along with "A. Piotrowski" and "Polski Store". He apparently was an agent for the Park Floral Company in Broad Street Park (in Hamilton Township, south of Trenton), and apparently dealt in Polish goods. From E-Bay ( Trenton). Item number 481764346
