This striking orange 2 fillér stamp was issued by Hungary in 1937 to commemorate a major medical or health-related congress held in Budapest. The central design features the caduceus, a universal symbol of medicine, above a flowing banner inscribed “Vásár 1937 Május” (Fair, May 1937), highlighting the event’s timing. The bold typography and clean layout reflect the graphic style of pre-war European commemoratives. Inscribed “Magyarország”, it represents Hungary’s contribution to international medical cooperation during the interwar period. A visually appealing thematic piece for collectors of medical, conference, or European classic-era stamps.
