This is a lithophane lamp made from ''Wapen van Nederland met motto: Je Maintiendrai, Henricus Wilhelmus Couwenberg, 1830 - 1845''. It was an entry in the Rijksstudio Award in 2015. The image is an etching in the Rijksmuseum in the Netherlands.
To make this a lamp you can glue in a fitting and attach a wire through the bottom. There is a file (WireClip) you can use to glue the wire to the bottom. I recommend to use LED lights as they don't get so hot.
