I swapped some emails from this person, and she seems very legit. She had a bunch of questions about Catalin/Bakelite/Clay, etc., and seems to be very concerned about not misrepresenting anything.

She works in the movie industry, and has access to the props department at a major studio. All the chips were used in one movie or another, you'll get a certificate that names the movie. However, they may have just been sittig on a shelf in the background of one scene that had nothing to do with poker, but darn it, they were in the movie!
