There were many variations of the Jolly Roger

Not every pirate ship boasted a skull and crossbones, but most of them had some form of what is famously known as the ‘Jolly Roger.’ Blackbeard, for example, had a white skeleton devil thrusting a spear through a red heart. Some ships had red skeletons on their flags, some had pirates standing on skulls, hourglasses and skeletons, it was different depending on the crew. They were all pretty bad@$$ though.
