View of a Mitchell car pulling coal cars. Label on back: "From: Mitchell Motors Company, Inc., Racine, Wisconsin. Puling a train of six coal cars in high gear is the everyday routine of this new F-50 Mitchell 'White Streak,' owned by Beamer & Smith, Mitchell dealers at Uniontown, Pa. This feat was more than a mere [undecipherable]. It proved to be a mine superintendent that the F-50 has a 'flow of power' and as a result three cars were sold to executives of one company." Handwritten on back: "Mitchell."
