The Hereditary Grand Duke, Prince Guillaume and Princess Sibilla at MUDAM

Guillaume was at the Museum of Modern Art to aid in the presentation of the Edward Steichen Award. For some reason it is not mentioned on the official website that Prince Guillaume and Princess Sibilla were also in attendance.

Manuel Dias has a gallery of photographs of the event.

Guillaume was wearing his wonderful beautiful beard. He seems to have aged recently - for the better. I think that retailers in Luxembourg should start refusing to sell razors to Guillaume. ;)

The official website also has a mention of the forum that The Grand Duchess and Princess Margaretha attended with a few more photographs.
