Detlef Hagenbäumer "at night". Original color lithography. Plastic effect due to a double print with lithography on paper and a black overpressure on the glass. Hand signed and numbered (1/1). Hanging framed in an aluminum frame. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
