American Political Cartoons, 1754-2010 book

Until I met them today, I didn't realize Stephen Hess & Sandy Northrup, the authors of American Political Cartoons, 1754-2010, were both in the DC area. Sandy tells me that they'll be making at least three appearances, "speaking at the National Archives, April 13th, 7PM; Library of Congress, April 27th, 12PM and; Newseum, May 15th, 2:30PM. It should be a lively discussion accompanied with a power point presentation." I plan to attend at least one and will buy the book, which is an update of the first edition (that I already have).
