Mr. Stewart and many others, including Janet Leigh, Spencer Tracy, Fredric March, Jane Wyman, Claudette Colbert, Kirk Douglas, Jackie Gleason, Burt Lancaster, Esther Williams and others, appear on this 1958 disc (108156B). The disc was issued to radio stations on a 16-inch, 33 1/3 RPM record.
Stewart also appeared in “This is…” announcements in 1957 and 1959. The PSA’s are called this because each of three or four celebrities simply say, “This is,” and add their name. The final person also delivers a short message.
The 1958 disc is not in general circulation, but is available at the Library of Congress.
