This is one of the "Dime Line" 3-D paper ship models made by Reed & Associates of Chicago. The assembly sheet, which measures 20" x 7" is in absolutely mint, unpunched condition and even comes with an "errata" to the instructions for assembling the battleship model. The envelope it came in also has a great color lithograph of a battleship on it's front. The only distractions are edge tears on the "opening" end of the envelope. Great WW-II paper toy!
