Well, I guess the elderly couple that brought in the chips could have been lying. They said the chips were bought by Jack Warner when he lived in Beverly Hills - not Sam or Harry Warner. Also gift shop items are not usually ordered by the President of the company. I believe Warner Brothers was located in Burbank, not Beverly Hills

If the chips were movie props, again, they would have been ordered by the company in Burbank. There would be no mention of Jack Warner or Beverly Hills.
