The photo was taken on the top of Ball Building, Paramount lot, Hollywood. Before that particular lot was the Paramount studio, it was the Desilu studio, and before that, it was RKO (Radio-Keith-Orpheum). RKO Radio Pictures Inc. was one of the Big Five studios of Hollywood’s Golden Age. They made some notable films in the 1930s and ’40s. During the 1930s RKO produced the well-known Fred Astaire-Ginger Rogers series of musicals and the early films of Katharine Hepburn.
