Tom and Jerry pass by two movie posters for cartoons that don't exist: Dial "M" for Mouser (with Tom and Jerry) and The Sand Pauper (with Droopy, wearing a cowboy hat and vest)
This is one of the only two Tom and Jerry cartoons where William Hanna and Joseph Barbera worked at MGM Animation/Visual Arts with head president and producer Chuck Jones and supervising director Tom Ray featuring the original staff animators in the Jones era since Tot Watchers (1958), released in 1958, after the two started focusing television animation projects since Big Mouse-Take (1965), the last H-B short ever to be made.
Tom and Jerry are animated using their original designs.
The roller skate seen early on was the standard style children used. It adjusted to the shoe size with the use of a skate key. Shoe in street models (with metal ball bearing wheels) would follow, the forerunner of the modern roller blade.
