Once again, beautiful attention to background detail here, one of the hallmarks of animation's golden age. The exposed brick under the building's plaster, Jerry's detailed mouse hole door with its small light, the Canary's furnished birdhouse, even the shadows cast by the open windows on the structure behind, all are drawn with careful precision.
A gag similar to that of Tom trying out his bat-like wings, then crashing into the mailbox after looking at the viewer, is present in the Road Runner cartoon "Gee Whiz-z-z-z-z-z" (1956). In this one, Wile E. Coyote also tries out his bat-like wings before crashing into a cliff after he, too, looks at the viewer. Moreover, both scenes were animated by a Ken. Ken Muse for Tom and Jerry, and Ken Harris for Road Runner and Coyote.
The cute yellow Canary like bird seems to be a combo of Tweety and Lil' Quacker.
The end scenes were a likely nod to the WB duo of Coyote and Roadrunner, as Roadrunner always got away in the end, sometimes with the help of planes, trains, or automobiles.
Tom's wings are actually an old fashioned corset undergarment, used in an unconventional new way. It slipped past the censors of the day, probably because of the humor involved. Showing undergarments in general were just this side of the censorship rules, even for cartoons.
