It's evident from my stamp collection that it is the USA that features its flags the most. However in Great Britain it was 2001 before the Union Jack appeared on a stamp as the subject in its own right along with the White Ensign in a series on the submarine service.
!962 was a World Cup year, Chile was the host country and the cup was won by Brazil.
It was Hungary however who had a series of stamps showing the competing nations.
