eBay
I am in the process of selling my original, black-border collection of Call of Cthulhu CCG (now Call of Cthulhu LCG) cards from Fantasy Flight Games.

BONUS: 
IF you win this auction and my other four Call of Cthulhu sealed product auctions (an Eldritch Edition Booster Box, a Masks of Nyarlathotep Booster Box, an Unspeakable Tales Booster Box, and a lot of 25 Arkham Edition Booster packs), I will be able to ship in a flat rate box and add a second Conspiracies of Chaos Asylum Pack III (sealed), an Arkham Edition Premium Starter Rulebook, AND an artist's proof from one of the cards in the Conspiracies of Chaos set.  See the first BONUS MATERIALS photo above.
IF you win all 11 of my current Call of Cthulhu CCG auctions, then I'll throw in a set of 10 green plastic Terror symbol tokens which read "Call of Cthulhu LCG Gen Con League 2009" on the back AND a bag of all the remaining limited edition CoC CCG Faction tokens I have (11 Miscatonic, 19 Syndicate, 22 Cthulhu, 13 Hastur, and 25 Yog).  See the BONUS MATERIALS 2 photo above.
If nobody wins the bonus items, then I will auction them off in a few months.

This auction is for one sealed Conspiracies of Chaos Asylum Pack III from Fantasy Flight's Call of Cthulhu CCG.  The cards in this set are black bordered and have been out of print for many years.
This product is new and sealed in its original packaging.

I do ship internationally.  I do combine shipping.  I do offer shipping insurance.
If you have other questions, please check out my posts in the Call of Cthulhu LCG Trade Forums at Fantasy Flight's webpage.

One last thing:  this is my LAST set of Call of Cthulhu auctions FOR AT LEAST A FEW WEEKS.
