John Lorin Black (1894-1963) was a Cleveland artist specializing in watercolor painting. He is best known for lively action works of polo. Rebeck's "portrait medallion relief" of John Lorin Black was accepted for competition in the 1930 Cleveland Museum of Art "May Show."
Despite no finished work has yet been found, the editors of this site suggest this casting represents the 1930 May Show entry based on it's style and that it was preserved in Rebeck's estate.
Steven Rebeck and John Black were friends for many years as they are know to have collaborated on a Statute of Moses Cleveland in 1916 (see listing in "Works").
