Here is David LaFuente's awesome cover.
You can preview the work of the other artist's at Comic Book Resources, but here are two of my pages, colored by Sunny Gho. You can click through for larger versions.
Special thanks to iFanboy for picking the issue as one to check out this week.
"I can't think of a better way to celebrate 150 issues of one of the longest running, consistently great titles Marvel publishes than the artistic tour de force that Brian Bendis pulled together. Joining series regular artists LaFuente and Pichelli are two of my favorite artists: Jamie McKelvie and Skottie Young. Throw in a fantastic artist I would never have thought [I] would [see] on Spider-Man -- Joelle Jones -- and this extra huge issue is clearly one to pick up, even if you've never read an issue of Ultimate Spider-Man before."
Pages will be for sale, please enquire through the regular joellejonesart[a]gmail[dot]com address--though the page with Spidey above is already claimed.
