Stan Lee's story (Buscema art) features Thor in his only appearance in Silver Surfer (1968). A Thor movie is slated to debut next summer.
I had Stan Lee sign Silver Surfer #4 at the Phoenix Comic Convention on Sunday, 5/30/10. Although I didn't tell "Stan-the-Man" what writing instrument to use, he was smart enough to pick a beautiful Silver Sharpie to make his mark. The color is perfect on the dark purple background and I'm sure this item will be treasured for years to come.
