DURANT, Okla. (KTEN) — Starting on July 19, Texomans can expect to get a glimpse of Hollywood history in an event hosted by the Choctaw Casino and Duncan's Auctions.

"These things go in a drawer or something; nobody knows what they are what they meant to them. Trying to pass along the passion of what they were to the actual original owner," said Duncan's Auctions President Rick Duncan.

Memorabilia items from Elvis Presley to ZZ Top — and even a former United States president — are expected to be auctioned off at the Choctaw Casino, offering a glimpse of what some refer to as one-of-a-kind pieces of Hollywood history.

"The most unique items we actually came across didn't even know about them when we purchased the estate or obtained the estate for the auction," said Duncan.

On offer will be letters from movie stars like John Travolta, musicians like Paul McCartney, and even a speech that President John F. Kennedy was scheduled to deliver before he was assassinated in Dallas.

Duncan said the items are worth an estimated $17,000 to $100,000.

There's even some Texoma history available to bidders, including original Sherman Texas Instruments design plans from the 1950s to 1960s that led to the original digital calculators in the 1970s and 1980s.

"The more you dig into an estate or a collection, you see so much more there that has such a value to, you know, society and culture," said Duncan.

Hundreds of bidders from across Texoma and as far as Oklahoma City and Dallas-Fort Worth are expected to take a trip, call, or go online.

"Some of these items will already have bids against them before the auction even starts, and that's where we'll start the bidding at," said auction associate Dwayne Marchbanks.
