The Trades Union Congress (TUC), along with Guy Atkins of Goldsmiths University, has launched a best banner or placard competition for the 20 October 'A Future That Works' anti-austerity march and rally in central London, with parallel events in Glasgow and Belfast.
The Make our March contest - judged by artist Bob and Roberta Smith, comedian Josie Long and the Mirror's Kevin Maguire - is offering five £100 prizes for the most creative or funniest contribution to the event.
Make the March is asking people to share pictures of their protest art beforehand to get everyone talking about the importance of 20 October. All material uploaded to the Make the March website will have a chance of winning. It's not just placards, there'll also be a prize for the best graphic or video uploaded.

TUC General Secretary Brendan Barber said: "The evidence is mounting that austerity is failing. More than 2.5 million people are out of work, a further three million are not working enough hours to make ends meet and wages have been falling every month for the last three years.
"Saturday is a great opportunity for people across England and Wales to add their voice to the growing chorus of people who want an end to austerity and a fairer, stronger economic alternative.
"We are working closely with the police and other authorities to make a safe, well-stewarded and family-friendly march. People from all walks of life - from unemployed youngsters to seasoned campaigners - will be marching together for a future that works. I hope you will join me on the march on Saturday."
