This piece by crochet artist Olek is on the walls of the Village Underground in Shoreditch, London and was completed in conjunction with the Street Artists Against Slavery for 'Follow Your Art - Street Art Against Slavery' in aid of the NGO Anti-Slavery International. The four panels of crocheted graffiti display a quote from Martin Luther King's Birmingham Jail Letter written in 1963 - it reads: 'injustice anywhere is a threat to justice everywhere‘.
