Original World War 2 business industry trade magazine vintage ad for KEARNEY AND TRECKER CORPORATION of Milwaukee, WI.  You'll Never Have to Study It, Son!  Mein Kampf by Adolf Hitler.  No lad your homework won't include any of these strange, foreign unwholesome teachings, all of us are fighting to make sure of that.  Making things better with light metals, plastics, and chemicals.  Old 1943 WW2 era propaganda magazine advertisement. Light stamp on left side of ad.  Would display nicely matted and framed.
