So DC is doing their road show to promote their upcoming books, including the new Sandman book. As a promo, they gave out Superman Unchained #1 3d variant. This isn’t like the old school needing glasses 3d from the past, instead thy are using new 3d lenticular technology. This is the same type cover coming up on their villains month books.
Within hours of the book being given out, one copy sold for over $400. If you can sweet talk your local retailer into letting theirs go, or they have one going for a decent price, this one would be worth picking up and flipping.
