The parish will be producing a montage of images from those who enter their competition with the winner receiving the cup by the end of the month.
It is still currently being made but the idea was to award something ‘a bit special’ for people getting involved in the islands’ scaled back celebrations.
The constables are hoping the St Peter Port parish will get on board and put as many entries as they can in.
Constable Zoe Lihou said the decorations can be as big and grand, or small and subtle as people wished.
She said they were hoping to make this Liberation Day a big one and really show off the parish with a flourish.
‘Just because we can’t hold the celebrations on the seafront as we have in the past doesn’t mean we can’t mark the event,’ she said.
‘The constables want to see all the beautiful decorations put up in GY1 to celebrate this special occasion and of course people celebrating as well.’
The competition is open until Sunday.
Anyone wishing to enter will need to post their photographs and/or videos on Twitter, Facebook or Instagram with the tag #GY1together.
