That book is Sodomy and the Pirate Tradition: English Sea Rovers in the Seventeenth-Century Caribbean. Ref: http://www.abebooks.com/products/isbn/9780814712368
The cover art lacks the flamboyancy that one might associate with pirates. Or a kind of pirates, anyway. ... the best kind of pirates. Hmmm...
Oh sorry, got lost in my own thoughts. Anyway, I totally want to see some alternate cover art. I'd be willing to put up the dough to buy the book as a prize for whoever has in my opinion the best alternate cover, so that you too can put the book on your shelf and make people uncomfortable. Sorry, the prize book wouldn't have the alternate cover art!
GOGOGO!
