Where or where does one begin. I would almost guarentee that the one most misidentified items being sold as "authentic" would have to be the copies of the Honolulu Star-Bulletin from Dec. 7th.
Now this is a guess, but I would have to say that over the years hundreds of thousands if not millions copies of these papers have been reprodused and sold at museum shops and so forth.
During my last trip to Hawaii, while at the Arizona Memorial Visitors center, I sat ad watched at the book store as to how many people came out of there with a copy of this paper. 17 out of 20 people I counted bought one. The reason...they are cheep. Only a buck. Think of how many people go through that visitors center in a year, and if 85% of the people are buying a copy of this, these copies are all over the world.
Now Sally-Joe-Mike whoever takes one home as a souviner, and it gets placed in the back of a cabinet for a few years, and forgotten about. Years down the road it is found, and sold on a rummage sale to another individual, who holds onto it another few years, and sells it or gives it to a distant family member. Before long, no one knows where this has come from, and they think it is original. And in turn sells it as an original. Someone who doesn't know what an original "real" copy of this paper would probably end up shelling out quite a bit for this.
As I type this, there are fourteen copies of these being sold on Ebay. And only one states that it is a reprint.
Now talking about Ebay....currently (5-30) there are 2965 items related to Pearl Harbor being sold on there. This time last year there would have been maybe 600 at the most. Now the movie has something to do with this, but there are also so many individuals out there who are selling stuff they know not to be authentic. And they are selling it because they know there are individuals who will buy it. Buyer beware!
Guess I have preached long enough here. I just hate to see someone spend money foolishly on items that are either fake, or misrepresented to seem original.
My two cents worth.
