Description given with photograph: "Howard Hughes in New York after making a high altitude flight from Los Angeles during which he tested a two-ounce oxygen mask."
Back of the postcard. Some of the wording is not readable. It looks like the postcard was sent to a woman, Miss Stewart of California, from Paul Smith.
A rear view of Howard Hughes Grover Whalen, and Al Lodwick riding in the back of an automobile in a parade dedicated to Hughes for his completion of the round-the-world flight. Typed onto a piece of paper attached to the image: "Rear view of car in which Howard Hughes, Al. Lodwick, and Grover Whalen ride up Broadway after Howard Hughes flight Around the World. July 1938."
