Antarctica Treaty flag patch

Size: 6.5 x 4 cm (2.56 x 1.57 inch)

Prior to 2002, Antarctica had no official flag as the condominium that governs the continent had not yet formally selected one even though a particular design was in widespread use. The consultative members of the Antarctic Treaty System officially adopted a flag and emblem in 2002, which is now the official symbol of the continent (source: wikipedia)
