The card is not numbered, and as far as we can tell is not part of a larger set. The sponsors listed on the back are the USDA Forest Service, National Association of State Foresters, McKinley Volunteer Fire Department and Iditarod Trail Committee. The McKinley F.D. clue helps to narrow down the area where the card was originally distributed.
It's difficult to guess a value on this card, thanks to it's scarce and obscure nature. I could see the right Smokey or Iditarod collector paying ten to twenty dollars for a nice example.
