Give me the cover OA to Tales of Suspense #49 (Iron Man but guest-starring the Angel) and I'm good. I'll take the paintings off of the walls, give you my portfolios, and we'll call it even. You'll lose money on the deal but, hey, you'll have made a fellow collector very happy.
It's all nostalgia. Many years ago, my much older cousin had one wall of his bedroom lined with old comics -- before he hauled them all off to the dump, a couple of years later -- and he let me read the first comic he pulled out. It was, of course, ToS #49.
I was, maybe, ten, and the nearly-powerless Angel somehow grabbed my attention. I was a comics fan before the last page turned. An X-Men/Angel fan, too, but only old school; you know, the team that no one else cared about, the one that didn't set any sales records.
So, yeah, that one cover, I'm done.
