Ok, this is the thing. I just got what seems to be concept artworks -or original art- for 2 finnish posters (or trade ads, or something else).
The titles are "The female" (1933) directed by Michael Curtiz and "Bureau of missing persons" (1933) directed by Roy Del Ruth.
Both are made of cut stills and apparently drawn parts (the lettering and drawings).
The Warner and First National logos are the ones used in that era, and the composition would indicate they're indeed originals made for later printing of the posters. As I couldn't find any image of the finnish posters for this titles to see if these were the designs used, I have no way of telling what is it that I got.
The only other finnish Warner First-National poster from this era that I could find uses also stills, the film title in finnish and swedish and the logos:
