These three vibrant prints by Robert Indiana, published by Editions Denise René, are part of his *Polygons* series, in which the artist explores geometric forms — the hexagon, octagon, and nonagon — rendered with his signature bold colors and hard-edge precision. Indiana masterfully transforms these mathematical shapes into visually dynamic compositions, reflecting his deep connection to American pop art and his interest in numbers and symbols as carriers of meaning. Each work is hand-signed, dated, and numbered 29/100 in pencil, with an additional 25 artist's proofs issued in Roman numerals, underscoring their collectible significance.
