Preston DeCosta, 15 years old. Messenger #3 for Bellevue Messenger Service in San Antonio, Texas. October 1913. I ran across him while he was carrying notes back and forth between a prostitute in jail and a pimp in the Red Light. He had read all the notes and knew all about them. He was a fine grained adolescent boy. Has been delivering messages and drugs in the Red Light for 6 months and knows the ropes thoroughly. "A lot of these girls are my regular customers. I carry 'em messages and get 'em drinks, drugs, etc. Also go to the bank with money for 'em. If a fellow treats 'em right, they'll call him by number and give him all their work. I got a box full of photos I took of these girls - some of 'em I took in their room." Works until 11 P.M. View full size. Photograph by Lewis Wickes Hine.
