Die Erotik. (Die Gesellschaft, Sammlung Sozialpsychologischer Monographien herausgegeben von Martin Buber, Band 33)
The spine strip is in a parlous state, with both head and tail lifting, the front hinge has been reinforced with acid free tape, but the binding remains shaky and there is a neat ownership signature on the title page. Internally the pages are clean with no underscoring or annotations and provided it's treated with respect, it should las another 105 years.
