Authors Evenhuis and Landau use the term "challenge the Establishment" to describe Kellerman's "skimpy costumes" and nude movie work. If indeed this is a still from A Daughter of the Gods it captures the actress either dancing or in the middle of an exercise routine (1).
This picture is credited to A Daughter of the Gods but Kellerman is missing her long locks and tranquillity (AK1610). Exercise or dance, with a tight belly and scooped waistline Kellerman portrays a degree of sexual aggression with midriff that is timelessly hot but only comes to Hollywood in the late 1910s. And this is not Kellerman's only bare-midriff top (AK1L50).
Attributed to A Daughter of the Gods, Fox Film Corporation, 1916 by Frans Evenhuis and Robert Landau, Hollywood Poolside, Angel City Press, Santa Monica, CA, 1997. 1 picture.
