As cartoon shorts were shown as part of a cinema package in theater, they were made with adults in mind, as well as children. This is a perfect example of a more grown up theme, as movie goes would have appreciated all the bids to the big screen musical extravaganzas of the era.
The era of the large department stores, which sold just about everything, is portrayed here with both accuracy and humor.
Might have helped inspire the 1960 Twilight Zone "The After Hours" and the 1980's "Mannequin" film series.
Although the items portrayed might seem archaic to 21st century viewers, they were the very latest design at the time and would have been recognizable to film audiences of the era. In the years before modern product placement, it was a subtle and clever way to encourage consumers to buy the newest products.
