UNESCO the Cavern Club series of UK postage stamps Royal Mail United States Postal Service Yellow Submarine 1
On 16 January each year, beginning in 2001, people celebrate World Beatles Day under UNESCO. This date has direct relation to the opening of the Cavern Club in 1957. In 2007, the Beatles became the first band to feature on a series of UK postage stamps issued by the Royal Mail. Earlier in 1999, the United States Postal Service issued a stamp dedicated to the Beatles and Yellow Submarine.
