Produced in 1956, the Black & White print of "Men and Mail in Transit" shows all aspects of RPO service including several "catch on the fly" actions and much work in an RPO car. Also in 1956, the National Postal Transport Association B&W film "Mail in Motion" shows work in terminals, Highway Post Offices, Air Mail Fields and RPOs.

A bonus color film, "Delivering the Promise" illustrates the history of the US Post Office Department and US Postal Service.
