This optical illusion is of another level. Posted by the Household Cavalry in 2017, the buzz it had created back then has not gone down till date.
The Household Cavalry comprises two most senior regiments in the British Army: The Life Guards and The Blues & Royals. It is divided into the Household Cavalry Regiment and the Household Cavalry Mounted Regiment. Since 1660, the soldiers of Household Cavalry have acted as the monarch’s trusted guardians, as well as being the public face of the British Army both at home and abroad.
