Here’s an incomplete promotional spot (or “An NBC Preview”) for The Loretta Young Show. I believe it ran in the fall of 1954 to promote the second season of the dramatic anthology which had premiered in September 1953 as Letter to Loretta.
The title was changed in February 1954 and the series would ultimately run through June 1961. I’m not familiar enough with the series to identify the first scene but the second scene, which is abruptly cut off, is from the April 25th, 1954 episode (“The Enchanted Teacher”).
The full spot likely ran either sixty or ninety seconds but it could have run even longer if it was a special preview rather than a traditional promotional spot.
