The title, Egghead Rides Again, probably comes from the Max Brand western novel, Destry Rides Again, which was published in 1930. Two movie versions were made. One with Tom Mix in 1932, before this cartoon, and one after it with Jimmy Stewart in 1939.
The background renderings are carefully drawn, but look more like the wilds of Arizona (saguaros) or Utah (red rock formations) than Wyoming (Bar-None Ranch). It didn't matter, western genre films were wildly popular at the time and audiences would recognize these familiar sights.
Postage at the time of this short was 3 United States Cents.
Among the many desert plants depicted are the Saguaro, the Organ Pipe, the Beaver Tail, the Prickly Pear and Barrel cacti, the Yucca, and the Sagebrush. These plants were not all found in Wyoming, but were familiar sights in many a Western production of the era.
Either on or by this cartoon (it's impossible to tell for sure due to Blue Ribbon re-issues), the Warner Bros. shield is now making its famous zooming-in sound, a steel guitar glissando effect created by Treg Brown. Also, the end of the cartoon's music no longer bleeds into the closing; instead, a closing theme is used (for Merrie Melodies, it's a shortened version of the opening theme; for Looney Tunes, it's a remix).
"Porky's Badtime Story", the cartoon that follows this one, is the first Looney Tunes cartoon with these changes.
