Esther Williams, actress, at the plastic exhibit wears a fur coat in Los Angeles Jan. 31, 1945, that has been Calva processed. This process covers the modifications of the physical structure of the fibre of the pelt to imitate well known high priced furs. One of the most spectacular accomplishments of the Calva process is the transformation that it brings about on shorn sheepskins or shearlings to imitate beaver, seal, nutria, etc. (AP Photo)
