"My sculptural techniques for the characters' aging were handled by adding pieces of white modeling clay, which matched the plaster, onto the surface of each bust," Seiderman told Norman Gambill. When Seiderman achieved the desired effect, he cast the clay pieces in a soft plastic material that he formulated himself. These appliances were then placed onto the plaster bust and a four-piece mold was made for each phase of aging. The castings were then fully painted and paired with the appropriate wig for evaluation.
