This relief mural depicting Anne Frank writing in her diary under candlelight in the attic, was created by Dutch artist Cor Dam for the Anne Frank School in Gouda, Netherlands. Click image for a closer look. via
Cor Dam was born in Delft in 1935 and studied at the Royal Academy of Art in The Hague, Netherlands. During his career he has worked as a designer for Royal Delft and as a sculpture teacher at the Delft University of Technology. He is an accomplished painter, sculptor and ceramist. Below are a couple more of Dam's pieces as well as photos I found of his studio. He has a website, but it doesn't show much of his work.
