Well, I must say I was pleasantly surprised (and I stand corrected on the origination

) this morning to see a quick response to my email and I think you may be happy with the answer:
My original email:
Good Day Mr. Tigrett
I am trying to identify an item that was recently found and am having no luck and was hoping you might be able to tell me something about it. It is a small charm that was made to look like a ticket to an event in 1971 at the original cafe. Thank you for taking a few minutes to look at it and any help you could provide in identifying this item would be greatly appreciated.
Regards,
Dennis

DENNIS, VERY INTERESTING...AS I DESIGNED EVERYTHING IT LOOKS FAMILIAR...IT MAY WELL BE FRIDAY JUNE11TH PRE OPENING CELEBRITY UNVEILING PARTY...WE OPENED MONDAY JUNE 14TH TO THE PUBLIC....I WILL RESEARCH A BIT MORE .....
BUT IT IS PRICELESS TO HRC COLLECTORS AS ONLY 150 WERE MADE ...IF I (OR YOU FIND OUT) I WILL
WRITE LETTER OF AUTHENTICITY FOR YOU...WITH RESPECT, ISAAC TIGRETT FOUNDER AND CREATOR HARD ROCK CAFE LONDON , HYDE PARK CORNER JUNE 14TH 1971 AND HOUSE OF BLUES HARVARD SQUARE CAMBRIDGE MASS. NOVEMBER 23TH 1992
Amazing.

Celtex...Just an idea, but you should email Mr. Tigrett your contact info and explain that you are the actual owner and I was inquiring on your behalf so you can receive the COA if it can be authenticated. This might even turn out to be banner worthy if its 1/150.
