During its brief period of independence from 1921 to 1944, Tannu-Tuva produced a variety of exotic postal stamps. Brightly colored, depicting local themes, and often of an unusual shape, they were a favorite of collectors. Memories of the triangular stamps he collected as a child sparked Nobel Laureate physicist Richard Feynman's quest to travel to Tuva. This, in turn, led to his discovery of Tuvan throat singing, and to the introduction of this ancient art to Western audiences.
