Star of David, yellow badge and Nazi concentration camp identifying triangles surround a square with the word Dieu (God). The square is a piece of Nazi concentration camp prisoners’ uniform.
Tous Ensemble (All Together) has a barbed wire circlet centered on a patch of striped fabric, like prison uniforms, stenciled with "Dieu ?"("God ?"). Surrounding them are more patches shaped in single triangles or pairs forming Stars of David in colors the Nazis used to identify which category (Jew, homosexual, gypsy, for example) qualified a person for a concentration camp or for extermination. The stenciled numbers 1 through 6 are scattered around, a recurring motif that I take to refer to the six death camps and the estimated 6-million Jews killed.
