Original Marx Pre production Artwork Tractor Box.  SUPER RARE.  15x6x6" Box with original artwork for three sides of the box.  The pictures do not do it justice.  We believe this came from a auction of the Swansea Marx/Linemar Factory in England when it closed.  (see reg. plate on tractor).  Great find for a Marx collector or a Tractor collector.  Please email for questions.
