I saw this great photo on Houzz and fell in love with this poster. To my delight, I stumbled across it on ebay!
Apparently, this poster is a reproduction of an iconic WWII propaganda poster from the UK. The original poster was issued by King George VI to uplift the spirits of the British during the war.
Also works as a motivation for daily sanity!! Now, the hard part, there are 16 colors to choose from... I'm thinking Pebble Grey? I may need to repaint my office ;)
