This is a very interesting recent Estate find. This 3-D viewer with 165 pictures by Raumbild Vertrieb is fascinating! The images you will see with this viewer are not only steeped with historical German locations of importance and breathtaking Alpine vista's, they are also extraodinarily realistic, I felt it was the next best thing to being there! The book box is a little rough but the slides and viewer are in very good condition. Please look at all pictures carefully and ask any questions before purchasing.
