When I told my mother that we were visiting The Blair Museum of Lithophanes, her first question was, “What is a lithophane?” Not something that just rolls off the tongue, even on a good day. According to Wikipedia, a lithophane is, “an etched or molded artwork in thin very translucent porcelain that can only be seen clearly when back lit with a light source. It is a design or scene in intaglio that appears "en grisaille" (in gray) tones.”
If you still cannot picture it, just check out the photos below. Regardless, this treasure does need to be seen in-person to fully appreciate the collection. The museum is only open in the summer and fall, but on the plus side, free!
