In an October 7th post, I referred to New York's Center Theatre, at Rockefeller Center. The theatre was, in the 1950s, the home of a number of NBC television programs.
It had previously been a legitimate theatre (and had, at other times, been a movie palace). NBC took over the theatre in 1950, refurbishing it for television productions; it was used for such programs as the Four Star Revue, Your Hit Parade (in its early years), and Your Show of Shows (in its latter period). Certain NBC radio shows also aired from the theatre, including The Big Show, a noted 1950-1952 variety program which starred Tallulah Bankhead. The theatre was torn down in 1954.
In 1951 and 1952, my mother performed at the theatre--on the Hit Parade, and on The Freddy Martin Show (also known as the Hazel Bishop Show, after its lipstick sponsor).
In the postcard, above (date unknown), the Center Theatre is seen, at the center-right; Radio City Music Hall can be seen in the distance. The postcard is titled, on its reverse side, "Looking North on the Avenue of the Americas (6th Avenue)."
