Two albums and one folder. Very interesting archive from Dr. Messerli (Lausanne-based physician to the International Olympic Committee between the 1920s and 1960s) of over 160 documents, letters, CPs and postal stationery (including an album from Russia), registered airmail, with corresponding vignettes, various countries (Europe, Switzerland...) and Marie Curie series from the colonies. The Olympic Games of Antwerp, Amserdam, Berlin etc. from this period are covered, as well as the Winter Olympics.
