Marvel Comics writer Briand Michael Bendis has been posting various pieces of artwork on his recently created Tumblr account. While doing so, he revealed the covers for Avengers Assemble #7 and Spider-Men #5 (both of which he wrote). The former was drawn by Mark Bagley and features the Mad Titan Thanos, while the latter (which will conclude Bendis' five-issue miniseries Spider-Men) is drawn by Jim Cheung and features Iron Man and Nick Fury alongside Peter Parker (the 616 Spider-Man) and Miles Morales (the Ultimate Spider-Man). Both issues will be hitting shelves in September. Check them out below:
