Seymour Brandwein was apparently a Maryland economist who traveled around the country in the '50s and '60's and sent postcards with state maps home to his son, Billy. This card is from Indiana.

Hi–

I’m speaking at Notre Dame tomorrow here in South Bend. They have snow along the streets here which fell back in mid-January, so much that it still hasn’t melted! By the way I saw the Cuban bearded revolutionaries who are on a good-will tour to N.Y. and Washington, at National Airport,

Daddy

I buy these postcards at a Brooklyn flea market.
