Niki de Saint Phalle, a French-American sculptor and painter, explored vibrant sculptures and paintings through self-taught, experimental techniques. Her work evolved from visceral, gunshot-riddled assemblages to exuberant 'Nanas', harnessing playful shapes and vivid hues to celebrate femininity and whimsy. These pieces, alongside monumental sculptures, resonate with infectious joy, liberation, and a daring challenge to societal norms.
