Rare guitar believed to be a gift from Marie Antoinette is expected to sell for $84,000

A guitar thought to have belonged to Marie Antoinette is expected to sell for up to $84,000 at auction later this week.

A French auction house lists the late 18th century "Trianon guitar" as a rare type of instrument created in Paris around 1775. An expert with the auction says the guitar is exquisite aesthetically and technically and it will remain on display in France until Thursday.
