In past years, the Festival had featured products and related processes with a rich background of folk technology and folklore; most recently, the 1969 Festival had stressed wool and corn products. For 1970,the thematic presentations focused on dairy products as well as present day milk production. The Festival activities were complemented by an exhibit in the lobby of the US Department of Agriculture (adjacent to the Dairy area on the Mall). Festival visitors could see dairy cows being fed and milked, and could then follow that milk as it was transformed by craft demonstrators into butter, buttermilk, cheese, cottage cheese, biscuits, and blintzes.
The dairy program was made possible by the US Department of Agriculture and the Dairy Industry Committee of Greater Metropolitan Washington.
