The Keep Calm and Carry On poster was originally designed by the British Ministry of Information in 1939 as part of a series of propaganda posters intended to boost public morale during World War II. While millions were printed, it was never officially displayed and remained largely forgotten until a copy was discovered in a second-hand bookstore in 2000. Its simple design, featuring a white Tudor Crown and a bold typeface on a solid red background, quickly became an internet sensation. Today, it is one of the most parodied images in history, serving as a versatile template for countless variations of 'Keep Calm and [Fill in the blank].'
