I never made a print ad for Blackmarsh, like I did for the Majestic Wilderlands and Scourge of the Demon Wolf. But since James offered to include ads supporting various OSR projects in the back of Petty Gods, I figure I should make one for Blackmarsh as it is one of the few open settings available. As with the other ads this is a homage to Trampier's illustration in ADnD's Player Handbook.
