I know this item has some worth, but is it really as rare as the site states?
I think bclarkie has one and maybe the burntwire brothers as well? Can anybody else confirm they own one? The copy I have is not complete and partially used. I'm sure it's authentic. Along the bottom left side it reads "TSR HOBBIES    8003    7/32-3/8". One side has the 7/32" hexes and the other 3/8". It measures 35" (not the 28.5 as noted on the site) x 22.5". It appears it came folded once lengthwise, then three times along the width creating 8 sections approx. 11.25" x 8.75". One of these "sections" on the 7/32" side has a dungeon map drawn in pen. In addition the item has been fairly neatly "torn" along the length fold to create two 35" x 11.25" pieces...also one of the 11.25"x 8.75" "sections" has been neatly torn away making the item only 7/8 complete. I'll work on getting some pictures uploaded as well. If someone here has some interest, PM me and we can discuss it further...otherwise I'll just Ebay it sometime in the next couple of weeks. Thanks for any help you can provide!

@seeyouinescrow is ++rare only 8002 on viewtopic.php?p=75910#75910 seen + has different hex size on back not as listed http://www.acaeum.com/ddindexes/miscpages/dm.html

Just dug out one of our Hex Sheets. It is thick paper and measures 22-1/2"x29" and has 5/8" hexes on one side and 7/8" hexes on the other. It is rolled and was never folded. It says "TSR HOBBIES" in one corner but has no 8002 or 8003 number or copyright date on it.
