People say they have been left "heartbroken" after a decorative knitted post box topper created for VE day has been stolen.
Kingswood Town Council worked with local knitting shop, Yarn and Yardage, to produce the two elaborate toppers to commemorate the 80th anniversary of the end of World War Two.
In a post on Facebook, council bosses said they were "completely heartbroken" after a knitted Lancaster Bomber that formed part of one of the designs was stolen, and they are now calling for them to be returned.
"It's really heartbreaking because one person's spent hours doing that and everyone's been really excited to see the finished product," said Alice Twinn, from the council.
"The team and the local community are really upset that it's happened," she added.
"We've had messages from parents who take their children to see the toppers and they've been really disappointed to see that its been damaged in this way."
Toppers were also been created to celebrate Christmas, Easter and other big events over the last year – but this is the first time they have been significantly vandalised.
"When we started a lot of people said they would get damaged and we really wanted to challenge that because the community deserves nice things regardless of reputation and we've been really pleased that they've been so well respected," said Ms Twinn.
Carly Morrish is the owner of Yarn and Yardage and set up the yarn bombing group that made the topper.
"The team are already planning something to replace it and that speaks volumes of the people in this group because they will not be beaten," she said.
"Every time we have an idea we level up and draw on each others skills to make it bigger and better – our motto is that yarn will always win!"
The council said they have put in a request to the police for CCTV.
They have also invited anyone who is in possession of the stolen plane to hand it in to Yarn and Yardage where no questions will be asked.
