the 510 sketch is still the ultimate Campbell .
I remember when the original artwork, one of a kind, 1 of 1, the ultimate Campbell for Uncanny X-Men #510 was on sale at Graphic Collectibles for around $5k I believe and remained unsold until there was a promotional website sale down to around $4k. I passed on it an encouraged someone else to buy it who did. So, if anyone is interested in that piece which probably now has an estimated value of $10k-15k, I might be able help broker a deal.
Campbell Original Art is the way to go for super collectors of Campbell who have interest in crossing that bridge from mass produced (albeit sometimes limited print runs) comic books into the one of a kind original artwork, which are masterpieces and when compared to the graded comics, isn't that much overpriced at times when you really step back and think about what you're buying, getting and owning in original art vs comics.
