Purchased jointly by Grand Dukes George (above left) and Michael Alexandrovich (above right); younger brothers of Emperor Nicholas II, in 1897 for 140 roubles.
Two years after buying the frame Grand Duke George died tragically, aged 28, following a motorcycle crash. Grand Duke Michael, the darling of the Imperial Family, survived until the revolution. He was murdered by the Bolsheviks in Perm June 1918.
The frame was almost certainly bought by the brothers as a gift, possibly for a member of their family.
