The Carousel Twin Theatre was opened from 1972 to 1979. The closing ad is pictured below and indicates the place had a 7-year run. The opening ad was in 1973 so in reality it wasn't a full 7 years. The closing ad mentions The Parkway as the new Nicholas George outlet. The 1973 aerial photo shows the theater but I am unsure which end of the plaza it was on. If I had to guess I would say the north end.
