Liechtenstein Flag
 
Flag Description:
two equal horizontal bands of blue (top) and red with a gold crown on the hoist side of the blue band; the colors may derive from the blue and red livery design used in the principality's household in the 18th century; the prince's crown was introduced in 1937 to distinguish the flag from that of Haiti
