Help with identifying a reference.

At their "Census" page NGC list a reference for medals from the 1904 Louisiana Purchase Exposition, simply called "Hendershott" with no other information or link. I have searched and searched and searched and searched and............................well, you get the idea, I have searched but been unable to find this reference anywhere. Can you help??
1904 St. Louis World's Fair--the Louisiana Purchase Exposition: Mementos and Memorabilia by Robert L. Hendershott is about the best I can come up with.

1904 St. Louis World's Fair, Mementos And Memorabilia, Robert L. Hendershott, copyright 1994, paperback, 365 pages, heavily illustrated, with price ranges.
Bob actually attended the 1904 Expo which explains his fascination with the subject. "Mr. FUN" passed away in 2005 at the age of 106.
Bob Hendershott's reference is the key reference for the 1904 Louisiana Purchase Expo. When Bob passed away in 2005, John and Nancy Wilson wrote a great tribute and called Bob "The Great One".
You can buy the reference on Amazon:

The author is Bob Hendershott, and you can see an video with an interview with him at the Newman Portal.
Bob and his last wife Marjorie Owens-Hendershott were both long time good friends of mine and I'm sure of many, many others on this board (many of whom are very jealous of the thick mane of snow white hair that Bob still sported in his 100's). I supplied some items for photos for the catalog along with some input of my thoughts on pricing. The catalog does cover many other types of items beyond tokens, medals and badge -- banks, pinback, glassware of all types, photos, china, advertising, ephemera, games, weights, purses, tickets, spoons, on and on.
A fine gentleman!
thanks for the help, guys.
as often happens with me, as soon as my patience reaches its end I find my answers!!! such was the case here. believe me, I did really search but if you look at my "post" time and my "edit" time you can see it took exactly six minutes for me to find a link once I surrendered. again, thanks for the information, it seems as though Mr. Hendershott led an extraordinary life right to the end.
