Is Blackbeard ever shown having Whitebeard's jolly roger on his back?
Whitebeard's pirates got the tattoo of Jolly Roger out of respect or to prove their association to the pirate crew. It is safe to assume that Blackbeard didn't sport the tattoo as it wasn't compulsory for everyone to get the tattoo. So that would mean Blackbeard hasn't been seen with Whitebeard tattoo.


  Whitebeard's flag is that of a standard Jolly Roger with a large mustache and a cross behind it. Many high-ranked crew members bear the Whitebeard flag symbol on them, including Ace who is seen having it tattooed on his back and being extraordinarily proud of it.
