Liverpool will pay tribute to Everton on Sunday for the support they have given during the ongoing fallout of the Hillsborough disaster.
Despite being local rivals, Everton have completely stood by the Anfield outfit in their quest for justice after the horrific events in April 1989 which saw 96 Liverpool fans attend an FA Cup semi-final and never come home.
Findings from the Hillsborough Independent Panel have seen the original verdict of 'accidental death' quashed, with new inquests ordered to take place next year, marking real progress in the campaigning from Merseyside.
As a thank you and a mark of respect, Liverpool will place 12,390 cards on the seats at the famous Kop end, which will be held aloft just before kick-off.
The cards will form a mosaic which will simply say 'Thanks' and Liverpool managing director Ian Ayre hailed the 'unique' relationship between the two clubs.
He said: "I want to take the opportunity to thank (Everton chairman) Bill Kenwright and Everton fans for their continued support for the families and victims of the Hillsborough disaster.
"It is the coming together of the families, supporters and the city that has made the huge breakthroughs of the last 12 months possible.
"Rivalry on the pitch and banter on the terraces are healthy things and are an important part of being a football supporter in this city. They are an important part of the derby atmosphere.
"However, it is the unity of both clubs and both sets of supporters when it's most needed that make our relationship so unique."
Kenwright had previously given an address at the annual Hillsborough memorial service, held at Anfield, last month.
The idea to thank the Everton fans was the brainchild of Liverpool-born Daily Mirror journalist Brian Reade, who still resides in the city.
