This is an english card sent as an official from Japan.
On the back of the card: With their scarlet capes standing out against the drab greyness of a snowy winter's day, soldiers of the Life Guard, a regiment of the Household Cavalry, rides across House Guards Parade on their way to the Changing of the Guard Cerimony.
The Life Guards (LG) is the senior regiment of the British Army and part of the Household Cavalry, along with the Blues and Royals.
The Life Guards grew from the four troops of Horse Guards (exclusively formed of gentlemen-troopers until the transformation of the last two remaining troops into Regiments of Life Guards in 1788) raised by Charles II around the time of his restoration, plus two troops of Horse Grenadier Guards (rank and file composed of commoners), which were raised some years later. - in: wikipedia
