I've come to realize that my favorite stereoviews (and tintypes, too) tend to be very very spare ones, particularly of natural specimens, and the color of the mount plays a significant role too (matte yellow, orange and cream being the best!) I can flip through hundreds to find one I like, which finding one like this makes feel quite worthwhile...to my eye just stunning...formally (more rich and nuanced than photos convey) for sure, but also the spareness of the image turns the focus back to thecontent as well--and what tells a more complex and loaded story (many stories) of America past and present than corn?
6 7/8 x 3 7/16 and in very good antique condition, general light wear/light stains, I think all to the good.
