Information brochure for the South Wind Gasoline Car Heater made by the Stewart-Warner Corp..  The information included is general information on how the heater works, how it connects with the car's fuel system, Guarantee, authorized service stations and distributors.  It looks to have a form number from 1939.  My uncle worked on early cars so I suspect this was his.

All proceeds from the sale of this item will be used to send medical supplies to Bolivia by Mano a Mano.  Mano a Mano has been working in partnership with rural Bolivian communities for over 25 years building medical clinics, schools, roads and water projects where there were none before.  Add to your automobile collection and help others thousands of miles away all with one sweet purchase.
