Rainbow Liz is an original painting by Jules Muck, also known as Muck Rock. Executed in acrylic on canvas, the work measures 84 by 48 inches and showcases Muck’s signature blend of bold portraiture and street-art aesthetics. Known for her vibrant compositions and graffiti-infused style, the Venice-based artist often incorporates expressive color and urban symbolism into her large-scale works.
