Temple Mount Poster in National Geographic

Leen Ritmeyer mentions that the current (December) issue of National Geographic includes a poster supplement of the Temple Mount.  He includes a picture of the poster and tells a little bit about his role in its creation.  He links to the NG website, but I cannot find a way to buy just a single issue.  My guess is that a newstand copy would not include the poster, and that a subscription ($15/year) ordered now would not include this issue.  But if you already have a subscription, don’t discard the poster insert before realizing what a resource you have.
