Das grüne große Ei. 1971.
Acrylic on canvas, stabilized by means of a thin fiberboard under the stretcher.
Jensen 395. Lower right signed and dated. Verso of canvas reinforcement titled, and verso of folded canvas inscribed "ROMA", presumably by a hand other than that of the artist. 130.5 x 98 cm (51.3 x 38.5 in).
A drawing titled "Akt und eine Türklinke aus Watte" (Jensen 440), which already has the seated nude in background and the opening door in right, is also in existence, however, without the seated nude in right.
