A portfolio book I made a while back, when people still made portfolios. Each "page" was a window envelope that could display a project, and hold more elements of that project. The book is completely handmade, mostly with found materials.

Nathan Hinz portfolio on Behance: Each "page" is a window envelope that can display a project, and show more elements of that project. Allows for a quick overview and a rich presentation in one book. Completely handmade, mostly with found materials.
