An encampment of newsreel sound trucks in Indianapolis.

Back of the photo reads just “Indianapolis,” but with that many news vehicles gathered in one place, this scene is likely at the Indianapolis 500.

Photo itself was taken sometime between 1929-1934.

(and dude, check out the knickerbockers on the Fox Movietone and Paramount photogs…sorry to break the bad news Lenslinger, but Garanimals shorts were very uncouth in those days…)
