Hmmm, a new exhibition highlights the British experience of the Second World War by leading with the Keep Calm and Carry On poster… I really hope they also highlight that it wasn’t used:
An import from the Museum of Fine Arts in Boston, “Keep Calm and Carry On” showcases the ingenuity and defiance of the British on the homefront during the London Blitz. Of particular interest are colorful “propaganda” scarves designed by Jacqmar scattered throughout the show. In addition to covering up hair that suffered from shampoo rationing, the scarves also promoted a variety of patriotic messages in cunning ways. A pink scarf emblazoned with black script reading “Switch off that light, darling,” might read as a seductive come-on, but it also reinforced the importance of following blackout rules.
