Another vintage television advertisement which aired during an episode of Emerald City, a gay-oriented TV show which ran in New York City from 1976 to 1979. This ad for the 250 Book Center (250 W 42nd Street) and G&A Books (251 W 42nd Street) came from Episode 31, 1977.
Apologies for the poor audio quality, but keep in mind this is over 40 years old, and it was actually even worse before we ran it through the Super-Dooper-Capri-a-nator (TM).
