Here's one example:

I found this one odd. The font is cartoony and the whole thing seems satirical. Also, only a boat is being sunk. It doesn't emphasize the dozens or hundreds of crew members. Also, I'm not really sure what they were trying to do with the colors. They almost got red, white, and blue right, but not really.
Here's a much more (in my opinion) effective poster:

It emphasizes an individual life. The colors are dark and foreboding. It also seems like whoever is responsible for getting this guy killed is in for fairly spooky haunting.
Here's a third which is sort of a combination of the first two. The picture has characteristics of the second poster, but the text is like the first poster.
