FYI, Parris just got back from Denver, where she printed the long-awaited Baratheon and Lannister t-shirts. They look awesome, if I do say so myself.
I got the first ones hot off the silk screen, and will be wearing mine at worldcon.
Wonderful Moira Peters artwork, as with the earlier Targaryen and Stark designs: the gold Lannister lion on crimson, and the crowned stag of Baratheon black on gold.
