Donation record book from interwar Germany relating to Hans Muller, association Blood Transfusion Services Germany, 1933. A4 sixe book which includes a photograph of Hans Muller. There is one entry which records the drawing of blood and three tests (one for Syphillis) which took place in May 1933. Blood grouping was established as AB. There is rusting on the staples of the book and thus it is rather delicate.
