50 years ago, the way we navigated around Britain changed. The government had commissioned two designers - Margaret Calvert and Jock Kinneir - to create a unified way to lay out road signs that would make it easier for drivers to quickly read and understand signs, and these were rolled out across the countries to create a system that remains today.
50 year later, 42 of the UK's leading graphics designers and artists have paid tribute to this by creating their own versions of road signs - some funny, some thoughtful and some just taking the piss.
The project was curated by Made North and forms the basis of a free exhibition at London's Design Museum. The museum is also showing off some of Jock and Margaret's original designs including a version of the Road Works sign created for the exhibition by Margaret.
