The Crayon Gun Sculpture. When One Gun Gone students saw the Crayon Gun for the first time it made many of them reflect on their younger siblings, cousins and our own children. While any child is too young to learn about gun violence, some children learn far too young. By using children's crayons as the medium in the One Gun Gone mold we reflect on how we teach our young people about violence consciously and unconsciously.  Profits from all One Gun Gone artwork sales are used towards our Gun Buy Back.
