I had both of these titles, but not in these states:
Lansdale, Joe R. Dread Island. IDW Publishers, 2010. First edition hardback, #60 of 100 signed, numbered copies, a Fine- copy with slight wear at head and small abrasion to bottom board edge, in a Fine- dust jacket with slight wear, in a Fine slipcase. Supplements a signed, non-slipcased copy. Bought off eBay as part of an under $100 lot. Isajanko, A039aii.
(Crack at top is either a stray dog hair or a scanner artifact.)
Lansdale, Joe R. The Two-Bear Mambo. James Cahill Publishing, 1995. First edition hardback, letter T of 26 lettered copies, a Fine copy, sans dust jacket (as issued), in a Fine slipcase. Supplements a copy of the regular Cahill limited edition, which is distinctly less attractive than this. I saw a picture of someone else’s copy of this and went “That’s pretty! I need to pick that up!” Isajanko, A017aii. Bought off a fellow dealer for $200.
