Marie-Luise Heller (German 1918-2009) Raumobjekt 1969. Constructed Plexiglass Composition.

Height 15.75 in., Depth 12 in., Width 15.75 in., Weight 5.5 lbs. The piece is a three-dimensional object constructed from spray enamel paint on acrylic glass (Plexiglas), measuring approximately 40 x 40 x 34 cm. Heller is known for her transition to acrylic glass as a primary medium starting around 1969, often creating experimental abstract and ornamental works inspired by artists like Victor Vasarely and M.C. Escher. Abstract optical composition featuring bold spiral forms in deep cobalt blue and translucent golden yellow, screenprinted onto clear plexiglas panels. The work is constructed in a transparent cubic format, creating a dimensional, layered visual effect. The design plays with depth, shadow, and spatial illusion—characteristic of late 20th-century geometric and Op Art–influenced work.
