My e-book looks at several vintage nude modeling scenarios. The most extensive segment describes Bob Lichtman's Manhattan photo studio. Models regularly posed nude there for resumes, personal hygiene campaign ads, etc. My publication considers Jade Hagen, a nude model and actress who was perhaps Lichtman's favorite model in the early 1970s. Bob Lichtman opened his studio in 1964, at a time when few women were posing nude. Hagen was going through a transition period when she modeled nude to fund her fledgling acting career. She also made commercials for Bankers Trust and other firms.
