Fairly heavy condensed thick and thin lettering with distinctive terminals, and a clean casual but not sloppy flavor.
Not a lot of digital substitutes.

Two which share some trait/feel with the sample:

On the other hand, you could start with a condensed (or a combination of condensed and non-condensed) high-contrast sans like Radiant and recreate the quirkiest letters.

This is a cool poster. (Thanks Riccardo for bringing it to my attention.)

Would it be possible to post this on Flickr? I'd love to be able to add it to this group:

YES OF COURSE! PLEASE DO! Share the love!

Might be interesting to try and identify the person who did the poster lettering in 1940.
_VÅRUTSTÄLLNINGEN I NATIONALMUSEUM KONST KONSTANTVERK_ seems to be Swedish for _SPRING EXHIBITION IN THE NATIONAL MUSEUM CONSTANT ART WORKS_ A place to start might be the museum's website http://www.nationalmuseum.se/

That's "konsthantverk", crafts. As in

SPRING EXHIBITION AT THE NATIONAL MUSEUM
ARTS
CRAFTS

Unfortunately the museum library is closed for renovation at the moment, or I could have swung by to have a look.

Thanks Johan for the better translation than I was able to drag out of Google translate. I was puzzled by "constant art" but I couldn't figure out what it meant.
Don

It's fun what a single letter can do sometimes! :) I'd like to see the Constant Works at some point.

Could be quite an exhibition. Consider some possibilities. The constants of the universe: Pi, the speed of light, the Boltzman constant etc. Others could include???

A ratio of spam to legitimate posts on forums?

K=spam>legitimate posts but is there a # for K.

I'm thinking artworks that are never finished, but are constantly being worked on. Possibly by automation, or nature.

I had he same idea with Johan: Artworks in a "Work-In-Progress" state.
I can even imaging an exhibition room having multiple copies (sculptures, paintings) of the same artwork at different construction stages.
Even better: The "last-stage" artwork could be such that you can jump again to the first one and continue in circles :)
