On 26 March 2011, 500,000 people marched through London in protest against government spending cuts. The March For The Alternative was one of the largest demonstrations ever seen in the UK.
To mark the day, the SAVE OUR PLACARDS team asked people to leave their protest material at a tree in Hyde Park.
Hundreds left us their placards, banners, and costumes. And we've worked hard to find new audiences for the material since.
Below, people share the politics behind their slogans, their experiences of the demonstration, and thoughts on what has happened since in Con-Dem austerity Britain.
