Hollywood on Parade 3

Hollywood on Parade was a series of short subjects produced by Paramount Pictures between 1932 and 1934. They showcased the studio's stars both in newsreel-type footage (glimpses of Hollywood figures at premieres, parties, the races, etc.) and in new material such as sketches or musical numbers. The print quality of these isn't the greatest, but nevertheless there's some interesting stuff here. Also note that there's a numbering system associated with these shorts, but because some of the information I've found is conflicting and confusing, I just made up my own numbers to differentiate between them.
In this installment, Eddie Borden plays a mail carrier. He first visits Richard Arlen's house and delivers some letters to Dick and his wife. We also meet their baby and dog. Next, Eddie delivers a package, which we learn contains a puppy, to Mary Pickford. She gives him a lift to the studio and they hear Bing Crosby sing "Down the Old Ox Road" on her car radio. Naturally when they arrive at the studio Mary runs into Bing and they have a brief conversation. Meanwhile, Eddie visits Tom Mix, who is apparently going on a world's tour, to say goodbye to him.
