The Flag of Indonesia is a simple bicolor with two equal horizontal bands, red (top) and white (bottom) with an overall ratio of 2:3. It was introduced and hoisted in public during the proclamation of independence on 17 August 1945 at 56 Proklamasi Street (formerly Pegangsaan Timur Street) in Jakarta, and again when the Dutch formally transferred sovereignty on 27 December 1949. The design of the flag has remained unchanged since. The flag of Indonesia is graphically similar to the flag of Monaco, with a slight difference in the shade of red, and ratio of its dimensions. The flag of Poland has similar dimensions but has the colours reversed: white on top and red on the bottom. In both, the red is of a slightly darker shade. (Source: Wikipedia.org, CC BY-SA)
