You find all sorts of weird stuff in your classroom when you are a teacher. This is my favorite thing ever “left” for me when I taught my high school kids in Oak Cliff. The students were all pretty interested in our David / Marat lesson. Some chose to express their interest in a visual way. I have this framed on my wall now and will keep it forever. Someday I will write an essay on why this is one of my favorite works of art ever made.
