When John F. Kennedy married Jacqueline Bouvier on September 12, 1953, one of their guests told a reporter from Life magazine that the wedding was "just like a coronation."

Now a rare set of photos from their stunning Newport, Rhode Island affair is being shared with the public before they are auctioned off later this month.

Thirteen negatives, which are believed to be unpublished, were found in the home of freelance photographer Arthur Burges, a backup shooter for the occasion. His family uncovered the keepsakes in his darkroom after his death in 1993.

Boston-based RR Auction is selling the negatives in their original folder along with a set of prints made from those negatives on their website. Bidding began on September 26 and runs through October 15. You can check out some of those photos below or visit their website for more information:
