In the Charlottesville scene, the appearance of a New Deal "Works Progress Administration" sign on the sidewalk places this episode sometime during or after April, 1935, when that government program began. Most other Season 1 Waltons action can be placed in 1933 based on historical context provided in those episodes.
The first of three episodes to utilize the old "Baldwin sisters throw a party but nobody comes" plot point. It would be repeated in The Starlet (1979) and The Revel (1981), the series finale.
The Baldwin sisters are excited that the motion picture they are going to see in Charlottesville is their first "talkie". The theater's billboard advertises the film as "The Rhythm of The Rockies" starring Billy-Jack Bibb as "The Crooning Cowboy".
First mention of telephone operator Fanny Tatum.
Ike Godsey has to show John-Boy how to use a telephone as he's never used one before. It speaks to the poverty and isolation of Waltons Mountain that John-Boy would be seventeen before he made a phone call for the first time.
