 Its influence can be seen in the dismissive stare and overwhelming physical presence of the sitter in Pablo Picasso 's 1906 Portrait of Gertrude Stein . Picasso admired Ingres and referred to him throughout his career . His invoking of Bertin can be read as a humorous reference to , according to Robert Rosenblum , " Stein 's <unk> bulk and sexual preference " . Stein does not possess Bertin 's ironic stare , but is similarly dressed in black , and leans forward in an imposing manner , the painting emphasising her " massive , monumental presence " . In 1907 the Swiss artist Félix <unk> depicted Stein , in response to Picasso , making an even more direct reference to Ingres ' portrait , prompting <unk> <unk> to exclaim , " That 's Madame Bertin ! "
