Lovely D. Appleton & Co., NY Coral Stereoview, c. 1870s

I find the combination of these tightly cropped, side by side close up photographs of coral against the very pale blue mount very lovely and satisfying and I just want to keep looking at it. C. 1870s, mounted photos, D. Appleton & Co, NYC.

6 13/16" x 3 5/16" Good condition, with just a bit of curling to the mount.
