Eurogamer said:Naughty Dog's new Uncharted 4 trailer includes what looks like artwork from Assassin's Creed 4: Black Flag.
The image was spotted by Ubisoft Montreal employee Azaïzia Aymar, who works as Assassin's Creed's head of content. So you'd think he would know what he was talking about.

ND really needs to have a talk with their artists about their reference material. They've been called out on stuff like this several times now, both for environment art and character likenesses. Hopefully this gets sorted out quickly.
UPDATE:
Trailer reuploaded with new image

Statement from ND:
In our eagerness to get the story trailer out we made a regrettable mistake and didn’t thoroughly vet the art work used for an in game painting. We’ve already updated the trailer. We hold all artistry in high regard and take full responsibility for having allowed this to happen.
We want to sincerely apologize to everyone at Ubisoft, the Assassin’s Creed team, the original artist, and our fans.
