My Google-fu is failing me.

I am, as you may know, producing a book cover for my Typography class. It is an erotic work written in the 1940s, but not published till the late 60s.

I am considering the vexed question of what typeface to use for the cover lettering. I cannot find any images of erotic book covers published in the period. (This may be because there were none.) I am even having trouble tracking down any typefaces definitely used in the forties, or any book covers definitely produced then. Can anyone give me any hints?

Edit: Tijuana Bibles were produced in the period but are comic format, not books proper, and as such have a very different typographical style.

Aha! The 1934 cover image for Miller's explicit 'Tropic of Cancer'! (work-safe). Although it seems he hated the cover.
