Here's a Stereoview real photo showing boys with baseball bats standing outside the Waterbury, Vermont, Baptist Seminary as underlined on the back. This is very early from a series of Mt. Mansfield Camel's Hump Moss Glen Morrisville, published by L.G. Burnham, Morrisville, VT. This series is from the 1870s, and distribution was extremely limited. It measures a standard 7x3.375" and the condition is EX.
