This Ecto 1 is impressive not for its attention to detail, but because it’s made entirely out of paper! Part of Paper Inside, a paper model blog, the Ecto 1 model is just one of the extremely intricate paper models that are featured. Other notable models include the Back to the Future DeLorean, the General Lee, the Mach-5, and the Mad Max Interceptor. Each one comes with finalized photos to give you an idea of the end result, and pdf printouts if you want to try it yourself. Small hand and large patience are definitely required for assembly.
