Reddit user bruck7 decided to decorate his drab office walls with some fine superhero art — not by using painting methods or hiring an artist, but rather creating a mural with all of his co-workers out of post-it notes (8,024 post-its, to be exact). The Redditor posted an imgur album explaining his office’s accomplishment of creating a giant mural comprised of Spider-Man, Captain America, Wonder Woman, Iron Man, Superman, and Scarlet Witch.

Take a look at the mural and its process down below. Respect to bruck7 and his office workers for getting such a giant mural and project completed and getting paid for it!
