You have until Tuesday 1 March to nominate a Southwark icon for a blue plaque as the council's campaign to recognise the borough's hidden history enters its third year.
Southwark celebrities and historical figures and famous places or events can be nominated for a plaque. Shortlisting and voting will take place from 28 March 28 and winners will be announced later this year.
More than 13,000 people have nominated and voted for Southwark greats over the last two years.
"Southwark's blue plaques are truly 'people's plaques', as this is the only scheme in the UK that gets members of the public voting for their favourite icons," says council leader Nick Stanton.
"The campaign has already given us a glimpse of Southwark's vast heritage, but we've only seen the tip of the iceberg. We want to go further to unearth Southwark's hidden history and to get new people on the plaque shortlist who will fire the imagination of residents and reflect the great diversity of culture and experience that exists in the borough."
A shortlist of 40 nominations, five from each community council area, will then appear on the Southwark Council website and in Southwark Life magazine, with voting starting from 28 March.
