A petition to save a huge mural on the old BHS building in Hull city centre has received nearly 1,500 signatures.
Historic England previously said Alan Boyson's Three Ships will remain a part of the city's streetscape but it falls short of the high bar for listing post-war public art.
The petition has reached almost 1,500 signatures.
Hull Heritage Action Group, which has started the petition, says: "The external mural, 'Three Ships', has been a landmark in Hull since 1963. It was commissioned by the Co-operative Society and designed by Wolverhampton artist Alan Boyson.
"This large and iconic Italian glass mosaic mural immortalises the Hull fishing fleet. The face of the mural – which is fixed to a 66ft x 64ft concrete screen – is composed of 4224 foot square slabs, each made up of 225 tiny glass cubes.
"Inside there is a huge and beautiful fish mosaic also by Alan Boyson (for a long time this this was hidden away) thankfully it was uncovered after the property became BHS.
"Hull has lost so many architectural landmarks, please sign this petition. Together we will show Historic England how strongly we feel that Hull city centre needs to retain these mosaics for the future of Hull. Please Historic England these mosaics deserve to be safe and listed."
A Historic England spokeswoman says: " The mural is a distinctive landmark and is on Hull City Council’s local buildings list.
"We assessed the mural for listing and the Department for Culture, Media and Sport agreed with our advice that while the mural has its merits, it falls short of the high bar for listing post-war public art so will not be added to the National Heritage List for England."
