	During his time as an animator, having no formal training in sculpture, David began to experiment with different types of clay, and started sculpting the characters from those films he animated. He was then approached by Warner Bros. Studios, and commissioned to create a limited edition chess set, titled "Looney Trails", for the Warner Bros. Studio Galleries. All 50 sets, which required over seven months to complete, sold out within two days of their release. Following his initial success, Kracov continued working with the Warner Bros. studios, becoming the exclusive licensed sculptor for all Warner Bros. characters.
