I find these graphics to be absolutely fascinating. Trenton theaters has been one of the most requested subjects in my years as a historical researcher here at the Hamilton Library. Long before there was an RKO Trenton, Capitol, Broad, Princess, etc, there were numerous entrepreneurs who saw the possible profitability of establishing a "moving picture" theater. My research thus far shows that the Market Street Theatre at Market and Union Streets in South Trenton never got into the movie business due to union problems. numerous articles indicate that the building was used for meetings. During World War I, the area "Home Guard" held weekly meetings in the building.
Broad Street Park historian Jim Colello and I have been researching a movie theater that was supposedly located in Broad Street Park, but as of the present time we have been unsuccessful.
