My Man Godfrey (1936) has always been one of my all-time favorite films. The Godfrey of the title is a derelict (William Powell) who, after meeting wealthy and eccentric Irene Bullock (Carole Lombard), is hired as a butler in the zany Bullock household. It’s a really fun hour and a half, and if you haven’t seen it, I highly recommend that you do.
Godfrey‘s opening credits are very distinctive and very well-integrated with the storyline. The names (and titles, if necessary) of the cast and crew are designed like neon signs on buildings near the riverfront. The camera pans right, showing all the names in turn, ending on a painting of the city dump, where Godfrey, along with other “forgotten men,” makes his home. The painting dissolves into the first shot of the film.

I’ve included the screencaps below in case anyone wants to get a closer look.
The Godfrey typeface’s geometrical forms and low bars are very typical of the art deco type commonly used in the 1920s and 1930s. After some research, I think the closest you can get today is probably Semplicita Pro by CanadaType. You can “test drive” it here.
