On the back of the DCC Lankhmar box it calls out:
* Another 17 x 22 map of Nehwon

However, the maps (there were two in the box) are both 11 x 17. Is this a typo on the box? Or is there a 17 x 22 map of Nehwon that I failed to get?

Thanks.

Must be a typo -- all the open copies I've seen have an 11 by 17 map of Nehwon.
