Modeling Soap Sculptures in White Soap.

Postgate, Margaret. Modeling Soap Sculptures in White Soap. [New York]: [National Small Sculpture Committee]; [Proctor & Gamble]: [1926]. Single sheet, printed on both sides and folded, folded: 6-1/4 x 6-1/4 in.; fragile at folds, some splitting; together with Margaret Postgate, About Soap Sculpture (New York: National Small Sculpture Committee, [1930]), stapled booklet, [18] pp.

Postgate probably trained at the Art Institute of Chicago and Cooper Union in the early 1920s. After winning Proctor & Gamble’s annual soap sculpture contest in 1924, she designed ceramics for a number of companies, including Cowan Pottery.

OCLC finds no record of the former, a few scattered holdings of the latter.
