This cartoon is Beans the Cat's first Looney Tunes appearance, replacing Buddy.
The cartoonist's office has a water cooler, complete with glass jug. These are still in use in 2023, though the jugs are now made of lightweight plastic.
Farce au canard (1953) was still 18 years away, but this short may well have laid a foundation for the concept.
The last person to leave the cartoon factory appears to be a caricature of Ed Wynn in his Fire Chief persona, which was popular at the time of the cartoon's release.
The calendar that hangs on the wall of the cartoonist's office shows the present month as "Octember."
