It's a print, small frame. It depicts the Amarillo album, I believe, where the protagonist rides with some biker goats.
re: Prince Valiant... yeah that makes sense. I think I'll procure the single volumes, then. I usually don't go for old-timey art (anything before the 70s, in my philistine opinion) but Foster's art is just so damn gorgeous!
Ah yep that's the one. Thanks!
