There are some decent indicators we can look at when it comes to panel pages, how much similar KJ, or other big-time panel pages have gone in the past. I think a lot of them are apples to oranges (this compared to the first panel appearance of Wolvie to me is a tough comparison. I think these these are two different targets/buyers on era alone, let alone a bunch of other factors). I think some of them though in terms of overall value, are spot-on. Either way, I want this page, if it ever does go up for auction, to break records. I find it beautiful, and the perfect encapsulation of the tone that little aside story on the Joker had in the book. It's a proper museum piece.
I'm no expert. I'm happy I'm not, because it makes things like these fun, and I get to dodge the accountability. This has been a fun thread to lurk and read over the past few days, right, gents and ladies?
