They look to be offset prints (see the hash lines under magnifaction?) of etchings as shown by the  numbering notations. Artist looks to be C. Haaf 74. Thats just how they appear on my screen. Open one up and look for a plate mark.

If it helps at all, the title of the top picture is "Hochbahn ???strasse". It is obviously the name of the station, since Hochbahn means "elevated railway". Unfortunately it's a bit too fuzzy to read the crucial part of the second word. (I thought it might have been a Hochbahn station in Berlin that features in an old spy movie called The Quiller Memorandum, but it isn't).

I reckon the artist's name is probably "C. Haas", with the German long "s" that resembles an "f".
