Originals of most of these materials are also extant in the Clarke fonds.

This collection consists of three posters created by artist, Mark Podwal (b. 1945), to protest the Vietnam War. Podwal is well known for his drawings in The New York Times opinion page. In addition, he is the author and illustrator of books for children as well as for adults.
The three posters are printed on heavy cream paper with original pen, brush, and ink drawings by Podwal. All three feature quotations and were created sometime between 1965-1975:

1. “If anyone in days to come should say that we were civilized in this country, this war will be cited as proof we were barbarians.”
2. “To sin by silence when they should protest makes cowards of men – Abraham Lincoln.”
3. “November 15, Washington, D.C. – Blessed are the peacemakers: for they shall be called the children of God.” Created for or in response to the Moratorium March in 1969.

There have been two accruals. The first accrual arrived in disarray. The only series containing files in their original order are the Estate Accounting series and 2 files in the Feinberg series.
