Thank you Nigel for this awesome souvenir sheet, released on April 21, picturing the Royal couple official engagements photographs. There's some Welsh written on it too: Y Briodas Frenhinol, EUB Y Tywysog William o Gymru & Miss Catherine Middleton, which means The Royal Wedding, HRH Prince William of Wales & Miss Catherine Middleton. The stamps were unfortunately canceled on April 30. ):
All my wishes of happiness and longevity to the Royal couple
