This is not a quite recent trendy object in home decor, but has the modern style of the 40's that we all love. This poster is a replica of a WWII British encouraging people to keep calm during war time and bombings.
The poster was rediscovered in 2000 and has been re-issued by a number of private sector companies, and used as the decorative theme for a range of other products.
