Foyle MLA Raymond McCartney said: “This year it was decided by the party membership that the commemorative stamp should be in honour of Martin McGuinness.
“Martin has left to us all his memory, the legacy of his activism in our quest for a new Ireland.
“The annual Sinn Féin post has been a feature of the Christmas period in Derry now for over thirty years and I would encourage people to make use of it. Christmas cards will be delivered to any part of Derry City for the minimal price of 20p.
“The Christmas Post is now operating.Cards can be left at the Sinn Féin Office on the Racecourse Road Shantallow, Ráth Mór office on the New Road and at the Spencer Road and Strand Road offices.”
