The sounds of a typical day at Major Markets on Mermaid Avenue in Coney Island. Founded in the 1930's, Major Markets is a throwback to the days when the entire length of Mermaid Avenue, from Stillwell Avenue to Sea Gate, was a bustling retail strip serving a predominently Jewish and Italian population. Major's was one of the few survivors the area's downturn in the 1960's and 70's, and, later, the incursion of supermarkets. After closing his Mermaid Avenue market in 2009, Jimmy Prince, now 84, remains active. “Prince of Mermaid Avenue,” an award-winning film about Jimmy Prince by History Project Executive Director Charles Denson, is now available for viewing on his Coneyologist channel on YouTube.
