A big focus on Avenging Spider-ManVol1 issue #2 in that update of JoeMadArt.com!
Joe Madureira and Ferran Daniel (Colors) did a tremendous work on that comic (2011) and on my side I've been lucky enough to gather all the original pencil pages on internet!
For those that want to support Joe and read the comic you can buy the Avenging Spider-Man Vol1 issue #2 digitally on Comixology.com And if you prefer a physical copy it's still possible to find one in your local comic store.
Personally I order my comics from Grahamcrackers.com, they ship internationally and propose to save on shipping costs by sending your comics by set of 12.
Recently I've also received some emails of people asking me where it's possible to buy some original pages by Joe Mad!.
The best place for that is kwanchang.com.
Joe has sent him his pages directly for years so this is THE official place to buy them ;).
After that you will have to be lucky and search on all the big market places on internet.
That being said, you can have a try on comicartfans.com.
