andorra 6 cm round badge

The flag of Andorra (Catalan: Bandera d'Andorra) is the national flag of the Principality of Andorra and features a vertical tricolor of blue, yellow, and red with the coat of arms of Andorra in the centre. Although the three vertical bars may at first appear to be of equal width, the centre yellow bar is slightly wider than the other two so that the ratio of bar widths is 8:9:8 with an overall flag ratio of 7:10. A variant of the flag is said to have been created in 1866, although the design was standardised in 1993 after Andorra joined the United Nations.
