This just goes to show how little Dragonlance means to the Acaeum membership. . .
It is from the Time of the Dragon boxed set. There should be a product code of 1050 in the bottom left corner.
By the way Aneoth . . . virtually all TSR maps, cardsheets, counter sheets, etc. have a product code on them somewhere (with a few exceptions).
Just look for the first 4 digits and then compare it to the stock list on the Acaeum (or the TSR archive).
