Picture was taken c. early 1950s in East Atlantic Beach, View is to the east.
Jetty is on Troy Avenue. Big white building is the then Sea Isle Beach Club which was between Trenton and Nevada Avenues, right on the western border of The City of LB. Had other names as it was seemingly unprofitable no matter what it was named. Local legend says it was built by bootleggers during prohibition and was a receiving station for the refreshments arriving from sea.
A few years later it was named The Shore Country Club. That’s what it was when it burned to the ground. The blurry white stuff on the roof is big letters saying “Sea Isle”.
