A Connecticut company is selling a controversial artifact from the assassination of President John F. Kennedy.

John Reznikoff, of University Archives, is auctioning off a piece of the back seat from the limousine Kennedy was assassinated in back in 1963. Reznikoff has sold parts of the limo seat before, but the auction site was based in Dallas - adding to the backlash this time.

An identical piece, sold by Reznikoff to a third party, was listed on a Dallas auction site until Friday afternoon, but has been withdrawn.

“Out of concern for the sensitivity of the subject matter, Heritage Auctions decided to withdraw the lot from this weekend's Americana and Political Auction,” said Eric Bradley, a spokesman for Heritage Auctions.

At Dallas' Dealey Plaza, the site of the assassination, visitors said that was the right call.

“Well, that's actually pretty morbid, but they auctioned off the fence -- the original fence -- and it just shows you that, you know, anything's going to happen,” Mark Oates of Dallas told KXAS-TV.

“It's kind of sad that someone's still trying to make a buck off of that,” said Dealey Plaza visitor Keith Fowler. 

"There are rosy things that occur in history, and there are more macabre things that occur in history, but they're both part of history,” says Reznikoff. “And history needs to be preserved."
