To Smile in Autumn

by Gordon Parks.Norton, $11.95. “The ironic thing,” Mr. Parks observes in this partial autobiography, “. . . is that no country in the world offers a black the opportunities America does. The sad thing is that America makes it so difficult for blacks to take advantage of those opportunities.” Mr. Parks has taken advantage of every opportunity, succeeding as photographer, novelist, composer, poet, and film director. His sometimes dangerous adventures illustrate a further irony: a black who does take advantage of his opportunities is all too often viewed as a deserter by his own people. Illustrations.
