You can go ahead and file this papercraft Boeing 777, made entirely from manila folders by Luca Iaconi-Stewart, under the “incredibly constructed sculptures made from everyday materials” category.
From Junk Culture:
Using nothing but manila folders and dabs of glue, Luca Iaconi-Stewart has been putting together a very detailed model of a Boeing 777 that is almost as complex as the real thing. The doors open and close on paper hinges and the landing gear retracts up into the fuselage. The project which has been a labour of love for five years grew out of his passion for airplanes and the models he made from manila paper in a high school architecture class. Iaconi-Stewart told Wired, “There’s something rewarding about being able to replicate a part in such an unconventional medium.”
