"Sunday Painter" exemplifies Arman's signature accumulation technique, wherein he encases discarded art materials—paint tubes, caps, and gouache—within polyester resin to create a sculptural monument to artistic practice itself. By transforming the humble tools of amateur and professional painters alike into a crystallized form, Arman elevates refuse into fine art while simultaneously commenting on consumerism and the detritus of creative labor. Mounted on a metal base, this work celebrates the ritualistic, often modest nature of painting while interrogating the boundary between art materials and finished artworks.
