Hello all, thanks for reading...I have come across a Stereo Realist viewer w/box and slides. The slides date from 1950, and they are images of 1950 Nash Airflyte automobiles w/ interiors, engines, etc. I have tracked down Nash Viewmaster reels (and Cadillac), but I can't find any info on automobile advertising on Realist Stereo Slides. Does anyone know where I should go for ANY information on this rare lot? There are 12 slides with a typed piece of paper describing the images. Anything at all would be helpful, thanks in advance...I can post pics if that will help.
