Joel Barber's book Wildfowl Decoys. Getcha a copy. Not only does it have pictures of 2 originals Mr. Barber acquired direct from Mr. Dudley but it has a documented story of Barber visiting Mr. Dudley to purchase them. Mr. Dudley repainted one back to his original paint pattern, the only known example of a Dudley ruddy decoy with an original paint pattern. Also, Barber, being an architect, blueprinted many classic decoys in the book. Enlarged, these make amazing patterns.
Enjoy! Pat
