This lithophane was one of my earliest ones I made for my own collection.
Made from 2 images I blended together, one including an H.P. Lovecraft quote that I enjoy.

*all lithophanes I make come with a manual on/off 7w nightlight.  These do heat up, but I've never had any problems with them getting the lithophane too hot.

My lithophane nightlights are all roughly 5" on the longest side.
