On 15 March 2011, Luxembourg Post and Telecommunications will issue two new stamps. These stamps commemorate two milestone birthdays within The Grand Ducal Family.
Grand Duke Jean celebrated His 90th birthday surrounded by His family on 5 January. The Hereditary Grand Duke will celebrate his 30th birthday on 11 November.
No plans have been announced for Guillaume's 30th birthday. I hope that a milestone birthday falling on such a rare date (11/11/11) will merit an aptly "grand" celebration.
If you visit the P&T website you can view stamps issued each year beginning in 1999. Each year features a new stamp with the image or likeness of some member of The Family. Often stamps are issued in connection with a celebration...birthday, anniversary, ect...
