For sale is a PHOTOGRAPH of the undefeated 1947 Granite Falls High School Football Team (Granite Falls, Minnesota).  Little Sioux Conference Champions.  No publisher noted.  The black-and-white photo measures roughly 9.5 x 4 inches in size.  Good condition only.  The rather fragile photo has soiling, scuffing, creasing and edge-wear, and has been pasted against a blue, cloth-like backing.  There are two long vertical creases, which are especially noticeable.  The picture may have been cut out of a vintage yearbook, but that's only a guess.  A nice piece of Minnesota high school sports ephemera.
