James Pienkowski’s Robot is a perennial favorite in the pop-up universe. The entire robot family, from a newborn to grandpa, has an intricate full-color and full-page pop-up devoted to themselves. A first edition in Fine condition (the red shiny ROBOT title on the cover has disappeared in my scan, but is there on the book). Made all the better by paper engineer James Roger Diaz’s signature on the first page.
