Original 1950s German Railway Travel Poster

Don't know much about this poster, but I won it from an online auction. Purchase it for my bathroom (powder room) which I just remodeled, although it is not quite yet done, as you can see in picture 2. The poster is just the touch I was looking for. It is really really colorful in person. Here is what I know about the poster:

Signature illegible. Deutsche Bundesbahn - Sonderfahrt. Offset 1953. Size: 33 x 23.2 in. (84 x 59 cm). Printer: no information. Condition Details: (A-) small edge tears, tiny hole at the lower right edge.

Anyone?
