A "softcover book" Experimental Winchesters with Introduction By George Madis,8-1/2" x 11" with 43 pages of illustrations.There is a 2 page introduction stating that many of the guns were imagined pre-1914 and some of the illustrations are dated.The cover and one of the pages are shown.Some of the pages have more than one gun or idea represented.Any text is that which would have been written originally.There is no date or code but I have seen the date 1961 thrown around for the hardcover version. Excellent condition
