Information telebinocular viewers
I was wondering ... the approximate value of the collection listed as:
Keystone Telebinocular Viewers.
The Keystone System of Travel. Tour of the world. 1,200 stereo cards in book shaped boxes with 2 telebinocular stereo viewers with clip on incandescent illuminator and stand. Original bill of sale and a dated 1936. Accompanying book showing the stereoview titles, 185 pages. Approximately 70 lbs.
I was on the net trying to find the value of one set of the viewers and the boxes of cards that were recently found in a library that is under my direction. If you have any info let me know. I am attaching this photo of the viewers that were found.
