Hello folks - I painted these a looooong time ago, loved the constant stream of interesting figures that once popped out of the Foundry, well we, foundry.
I think most of these were sculpted by Will Hannah.... Here's a load more on the Foundry website.
These are clearly generic, but the site also had Edward Teach and all the other piratey goodness you could hope to find. There's a 2007 book by the British Historian Angus Konstam on him.
