With regards to the discussion of the 19th edition of The Paper Money of the United States; Art Friedberg did get John Nebel's superb images of the Bebee notes, among others from the ANA collection.
The special edition books (signed by both authors) are going to be on sale at Boston in the Museum Showcase area for $80 (including tax) right next to the Bebee display which is going to be there as well. If anyone wants a specific numbered edition (other than the first three), you can get it for an extra $15. Art will be available for personalized autographs Thursday through Saturday at times that will be posted in the Museum Showcase area.
