Early Television Museum
National Union 2031 Monotron
This monoscope was made in early 1938. It has an image which appears to be an advertisement for Saturday Night Serenade with Mary Eastman. This was a radio show in the late 1930s and early 1940s and may have also been a TV show. This tube was donated to the museum by Al Kozakiewicz.
