Belarusian graphic designer Lesha Limonov creates a currency-inspired series of sleep masks in his latest project titled Money Never Sleeps. Coming in three currencies – the US dollar, the UK pound and the Chinese yuan – the sleep masks are emblazoned with the eyes of Mao Zedong, Queen Elizabeth II and Benjamin Franklin. This isn’t the artists’ first foray into sleep masks, either: last year, he designed a series of sleep masks inspired by the masterpieces in Amsterdam’s Rijksmuseum. You can pick up these creative sleep masks online via Shuba Gift Factory.
