Max Klinger, Exlibris Dr. med. C. Schirren

Dear Sir,

I am interested in your newly listed exlibris for Dr. med. C. Schirren by Max Klinger.

Please can you confirm the following:

1. Is this an etching, not a heliogravure ? .... I know that this bookplate was reproduced as a reddish brown heliogravre in Braungart, (c.1920 Munich).

2. Is this an original Klinger exlibrids (etching) and not another "Reichdrucke" for some other period publication?

Thank you for your help with this.
