Band on the Run: I'm curious as to how a copy of his passport was obtained. Do we know for certain this a true document?
Here is what that photo looks like from a copy that looks like a trackable document. It is from http://www.christianwitnesses.com/id312.html
Note the hand stamping from the "agent - department of state". I suppose one could write to the state department and obtain, perhaps for a small fee, authentication giving the known information. I don't imagine a state department clerk will find it too difficult to find a record by supplying N. H. Knorr and a date of June 8, 1968. He's the only "Knorr" I've ever heard of. He's also the only Knorr I've ever met, tho briefly, at the 1957 Baltimore district assembly some 11 years before that photo was taken.
