This is an advertisement from the February 5-11, 1954 issue of TV Guide (the New England edition).
The ad refers to my mother's new weekly musical show on Boston's Channel 4, WBZ-TV; the program aired until the spring of 1955. The show was fifteen minutes long, and featured my mother's singing, as well as the singing of a vocal group, The Freddy Guerra Trio.
In addition to his work as a singer, Mr. Guerra was a saxophonist and clarinetist, and played, notably, with Glenn Miller's Army Air Force Band, during World War Two. Later, for many years, he was a prominent bandleader in the Boston area. (Mr. Guerra's first name was sometimes spelled "Freddie," as in the TV Guide advertisement. The other spelling appeared in a newspaper advertisement, below.)
Here is a newspaper story about Mr. Guerra, following his death in 2003:
