It's unfortunate that those are the letters you had, because only the R is much of a clue. Do you have more samples?

Thanks for replying. Not sure why I posted such a small sample, sorry about that. I'll attach the full poster. It's not Gill Sans is it?

Looks like lettering.

Ditto what Jan said: WPA posters were often hand-lettered. In the next few months, I'll be coming out with a series of typefaces based on WPA poster lettering, but none of them matches your sample.

Oh, I see. Beautiful lettering and funny coincidence that you're creating typefaces associated with WPA posters. Thanks to both of you.

Some ideas:

Berber
Futura Display
Gagarin Anna
FF Golden Gate/Moderne Gothics
Hotel, Fresno, Amboy
Jazz Gothic
Kaliber
Kanal
Morgan Poster
Nicotine, Liquorstore
Pacifico
MVB Solano Gothic Retro
LTC Tourist Gothic Alternate
Tropical Tourist
Turista GordaNF
Venacti
WPA Gothic

From Letterhead Fonts:

Stove Pipe Thin
Tallington
Quadrex

Thank you, those are excellent additions.

Also from Letterhead, Union Thug.

Probably the most common font used for this look on book jackets is Agency Gothic.
