![[Class of 1869]](http://www.mtholyoke.com/pcsite/photos/images3/Seminary10f.jpeg)
These stereoviews are great fun in a viewer. I can see why they were so popular in the last half of the 19th century.
There were so many different kinds of mounts (the cardboard backing on which the stereophoto is mounted) that I decided to group the photos by mount color and type.
