You are correct. The poker-playing monkeys were located in a window display at the Bowery entrance to Lillie Santangelo's World in Wax which operated in Coney Island from the 1920s until 1984. The museum also had an entire exhibit featuring Lina Medina, the world's youngest mother, a Peruvian girl who gave birth at the age of five.
The display of animated monkeys (they were actually chimpanzees) was called "Cheating Cheaters,"because all the simian players had extra cards hidden up their sleeves and under the table and were obviously cheating! After the waxworks closed, the displays were auctioned off and now reside in private collections.
