then f {z) is univalent f or \z\ < 1 . The object of the present note is to show that 2 is the best possible constant in (2) in the following sense: For every C>2 there exists a function f (z) such that f or \z\ < 1 we have (i) f(z) is holoniorphic, (ii) f{z) takes on the value one infinitely often, and (iii) | {f(z), z) | ^ C[\ — | z\ 2 ] ~ 2 with equality f or real values of z. An explicit example of such a function is given by
