In the 1990s, an exhibition of works by psychiatric patients took place in the Psychiatric University Clinic of the City of Zurich, Burghölzli, where we bought two work that where signed with A. Rüthemann and J. Lager. We liked them spontaneously but we knew and know nothing about their creators, and as only initials are added to the names, we don't know if they where done by men or women: for the reason of data protection, we do not know about the two artists and so no information can be given.
