Phatphreddy:
Glad you enjoyed them. Some background, if you're interested:
1st piece is for an Italian cigarette company which distributed widely in Central Europe. Its circa 1931, by a Hungarian artist named Biranyi, very rare. Quite large - about 35" by 55". Modiano posters are generally of very high artistic quality.
Last one is by Edmund Maurus, a French artist, from the 1920s. Air Union was a predecessor to Air France, and the Golden Ray covered an early Paris-to-London route. I don't have this one, though I'd like to - it comes from a West Coast dealer. It was restruck as a luggage label, and I have a couple of those. Many of the Air Union images are quite striking.
Several of the rest are from Germany during the revolutions of 1918-1923, all but one are commercial pieces (movies, German Pinkerton agency).
The 2d one is political - by an ex-pat Hungarian Mihaly Biro, who came to Germany after Bela Kun was chased out of Hungary, did graphic art for The Social Democratic party before turning to commercial work.
I have a number of other German political pieces from the Revolutionary period, both Right and Left, some of them quite over the top. Nothing you'd hang in the baby's room (unless it was Rosemary's).
