Group's bid to stop fly-posters.
Over the past six months more than 5,000 illegal posters have been pasted across the Southside Business Improvement District (BID), which encompasses Chinatown, the Gay Village, The Hippodrome anS The Arcadian.
Southside BID has now called on shoppers and workers in Birmingham to help identify event promoters and venues that ignore flyposting regulations.
Southside BID manager Julia Chance said: "Fly-posting is illegal for a reason. It dramatically affects the look and feel of an area and creates damaging litter.
"A number of our lasting murals have been blighted by fly-posters which make a negative impact on buildings across the district.
"We have tried reasoning with the venues concerned, all of which are outside of our district, but they blame the promoters and their guerilla tactics. It's time for venues and promoters to accept that fly-posting has to stop. We're calling on the public to support us by taking photos of the illegal posters and sending them to us so we can name and shame the culprits," added Ms Chance.
Photos of fly-posters can be posted on Twitter with the hashtag #cleanersouthside, or emailed to firstname.lastname@example.org
