Vexillography

The flag of Nepal is the only country flag in the world that is not rectangular in shape.

Vexillography (/ˌvɛksɪˈlɒɡrəfi/ VEK-sih-LOG-rə-fee) is the art and practice of designing flags; a person who designs flags is a vexillographer. Vexillography is allied with vexillology, the scholarly study of flags, but is not synonymous with that discipline.[1]
