The Prinzhorn Collection Museum is exhibiting variations on the crocheted face of a life-size doll, reconstructed by costume designer Erika Landertinger and art historian Claudia Schneebauer for the current exhibition »Alles Kunst? 25 Years of the Prinzhorn Collection Museum«. The original, preserved only through a photograph, belonged to the patient Katharina Detzel (1872–1960).
Erika Landertinger has also been working on the costumes for the new production of »Cyrano de Bergerac« at the Heidelberg Theatre and Orchestra. The doll and the play share one striking detail – the distinctive nose.

Further information on the exhibition »Alles Kunst? 25 Years of the Prinzhorn Collection Museum« and the anniversary programme can be found at www.sammlung-prinzhorn.de.
