I was actually wondering this myself...
I know I bought the original pencils to the cover, but it would be cool to own both.
I think ideally, it'd be nice to have both. Separately, the pencil piece has more value as the "true" original...but the blueline looks more finished. It'd be too hard to choose!
Still can't get over that a single copy of the comic is worth more than all the OA covers so far (sorry!).
I agree that the pencils are more 'original' and long-term, I think they'll be more desirable.
On the other hand, I like the look of the blueline and, as a more casual Revival fan, the $250 price tag is attractive. I don't think you can go wrong either way.
Congrats, Ash!
Absolutely. For re-sale value, I'd assume the pencil 'original' may be more valuable but they are both original in their own way. The blueline has details that the pencil doesn't that shows up in the final printed comic so it is unique in it's own way. I have only seen the pencil version up close of the one I bought and it's gorgeous. Looking at it online side by side with the blueline makes it look less desirable but I guarantee to anyone who gets the pencil versions, you won't be disappointed.
That being said, don't buy any of them until I make my next choice on which one I want.
