Up for offer from my private collection is this N.O.S. (New Old Stock) 1981 St. Paul Winter Carnival I-500 snowmobile race poster.  This poster is beautiful both front and back, not much more to say about it as far as condition goes.   As far as size goes this poster is 17- 1/4" x 22".   The posters front features the 1981 Yamaha SS440 Snowmobile, the St. Paul Minnesota winter Carnival, the 1981 I-500 snowmobile race which was the toughest cross country race at the time from Winnipeg Canada to St. Paul, Minnesota and The Hamm's Bear as well as the ever so important sponsor of the Race, Hamm's Beer.  This poster was issued by Theodore Hamm Company as can be seen in the lower right corner.  These type of posters for the I-500 are extremely hard to find and when you do see them they are usually used ones and not all that nice.
