It began as a collection of amusement rides and concessions in the late 19th century and was known as 'Chutes At The Beach' as early as 1913. It closed Labor Day weekend in 1972.
I remember going there many times as a youngster. My younger brother and I were always creeped out by the ugly head of a lady mannequin at the entrance to the park. She had chubby cheeks and a frozen smile, and her head bobbed up and down, with a scratchy recording of her laughing. It went “HA HA HA HA HA….scratch….scratch….scratch….scratch…..HA HA HA HA HA….scratch….scratch….scratch….scratch….." over and over again. I suppose the laughing lady was meant to put you into a cheerful, fun-filled mood, but it only terrified me and little bro. She was known as laughing Sal and has been preserved in the Musee Mecanique in San Francisco's Fisherman's Wharf, where she is still laughing and creeping out little kids (go to this link to see and hear her).
Here are some pictures of Playland at the Beach, taken over the many years of its existence.
