Though nearly impossible to photograph, Stanhopes are something you just have to see to believe. Before "viewers" and similar entertainment devices became popular in the 1900s, a French company produced these tiny Stanhopes that, when looked through like a small telescope, showed a photograph.
In the case of the offered Stanhope, the image inside is that of the great Old Tom Morris. It's really like a time capsule of viewing a 19th century Tom Morris photograph in its original form.
