Graig Kreindler is offering to produce a limited edition of his King’s Landing Map, which he produced for Meisha Merlin’s limited edition of A Clash of Kings. The limited edition will be printed on high-quality paper using archival inks. It looks like Graig doesn’t plan to make more than the total for those who express interest plus ten or so more. For an image of the map—which is gorgeous—see this image of it, even if it doesn’t do it justice.
