Exclusive: Disgust at Moygashel 'Marty rot in hell' poster
The message, which is painted onto a wooden board, also carried the words: "Moygashel celebrate the death of the Bogside Butcher."
As well as the transcription, the poster features an image of the Grim Reaper in front of two Union flags.
A local person - who wishes to remain anonymous - hit out at the image, which they said they found "disgusting" the day after the former deputy First Minister was laid to rest.
"I just think it's disgusting - at the end of the day a family are grieving," they said.
"It's just such a bitter statement to make after such a show of togetherness yesterday."
It is not clear how long the placard has been attached to the wall, but nor is it the first the village has drawn criticism for statements put up in the vicinity.
In 2014 police investigated a sign on the very same wall warning landlords in the area not to lease their properties to 'foreign nationals'.

The PSNI's Chief Inspector Roy Robinson said: "Police are aware of an offensive poster that has been erected in the Moygashell area of Dungannon and are working with people in the community to have it removed."
While local DUP councillor Kim Ashton said: "I am aware of the sign and am working with the community to try and come to a resolution."
Mid Ulster MP, Francie Molloy said: "As tens of thousands of people gathered in Derry to pay tribute to the life of Martin McGuinness, including Unionist leaders, US President Clinton, Irish Taoisigh (past and present) and representatives of the British government it is sad to see that a small corner of Loyalists have not moved away from the 1970s mentality that festered in the murder Triangle of East Tyrone and north Armagh.
"I call on the Unionist political representatives in the area to show leadership and call on the PSNI to have this removed without delay.
"Surely it falls within a hate crime. unfortunately this simply reflects badly on Moygashel and even the nearby Linen complex that attracts visitors and shoppers from all parts."
Story changed at 4.39pm, March 24 to add PSNI and DUP comments and at 5.02pm to add MP Francie Molly's statement.
