Masks of Nyarlathotep Unopened Shrinkwrapped Signed by Larry DiTillio 1984

Description

The legendary world-spanning Call of Cthulhu campaign from Chaosium #2307-X from 1984.
This box-set is new and unopened in shrinkwrap.
Item has been signed by author Larry DiTillio. The late DiTillio also wrote for TV, famously writing for He-Man and (along with J. Michael Straczynski) creating She-Ra.
I purchased this item in an auction at a science fiction convention in Los Angeles that was also a fundraiser for Indian Ocean tsunami relief in 2005.
Item appears essentially perfect in tight complete shrinkwrap. A couple corners look bumped, but that may be how they came off the factory line. The Sharpie-style signature is big and clear. See the closeup photo. It looks like the signature has been slightly erased in a couple spots, or possibly the plastic squeaked under the pen and skipped.
