This is pretty clever. I almost just scrolled right past this MOC, I suspect you almost did the same, but take a closer look. The roof and back of the cab is a book, and the windows are pail handles. The bottom of the cab is actually inverted, somehow the gap between the cab and the trunk is perfectly filled by the book half and I have no idea how this whole thing is held together. There's actually a lot of really slick building in this tiny hot rod by grantmasters.
