This is another photograph from the magazine article, referred to in the prior post, about Peter Lind Hayes and Mary Healy, and their early television show Inside USA with Chevrolet (1949-1950, CBS-TV).
The picture features, left-to-right, the television show's producer (and the noted composer) Arthur Schwartz; Mary Healy; and Peter Lind Hayes. As the caption notes, of Schwartz, Healy, and Hayes: "All have discovered that this new medium demands terrific stamina."
(As noted in the previous post, I do not know who took the magazine story's photographs.)
