Warren Bernard's Herblock Lecture

Warren Bernard writes in:

I recently did a lecture at The Library of Congress on the cartoonist Herblock, incorporating a history of the art of the political cartoon. The lecture focuses on the work he did prior to coming to The Washington Post, a body of work that spanned 20 years of which little had been seen prior to the publication of "Herblock:The Life and Works of The Great Political Cartoonist". There is a DVD with this book that contains all 18,000 of his known cartoons, which I edited.

For those of you so disposed, here is the video of the lecture:
