1960 International Olympic Committee: Signed letter from Otto Mayer on 57th Session I.O.C. letterhead, and enclosing card signed by 8 Ioc members - Armand Massard, Conte Paolo Thaon Di Revel, Dr Karl Ritter Von Halt, Avery Brundage, The Marquess of Exeter (Lord Burghley), Vladimir Stoitchev, Bo Ekelund and Otto Mayer. (Mayer apologises Baron de Coubertin died in 1937 and it is therefore difficult for me to get his signature!)
