I am pretty sure that the photos of marie and her two eldest sons is from the time of their joint confirmation. I am at work and do not have the actual date of the ceremony but it occured in either late February or early March in 1904. There was an interest article on the front page of the "Illustreret Tidende" for February 28, 1904, which describes the young princes and how Aage plays the Violin & Axel the Violin-cello.
