This promo photo was made for the 1933 pre-Code musical Footlight Parade, which, as the image suggests, contained some fairly racy scenes. James Cagney is in the center here, with Ruby Keeler at left, two actresses we can’t identify, and Lorraine Marshall at right. Movies made in 1933 and before are generally considered pre-Code, but the Hays Code censorship regime actually was created in increments beginning in 1927 before reaching something like final form in 1930. Few people had any interest in enforcing it right away, so it didn’t become rigid until 1934, at which point it successfully shackled cinematic expression for thirty years, until Hollywood was driven to imitate the envelope pushing films coming out of Europe. The Code covered anything and everything: drugs, profanity, ridicule of the clergy, defeat of the law, and more, but of course it was primarily designed to block sexual material, which means that in practical terms, Cagney never got to be the center of a sandwich like this in a photo again.
Life sure was nice before the prudes came along.
