A piece of royal history!

A unique collection of never-before-seen photos from Princess Diana and Prince Charles' July 1981 wedding are set to hit the auction block this fall — and we've got 13 of the stunning images!

The candid snapshots show bride Diana — who sadly passed away at age 36 in a 1997 car accident — and groom Charles, now 66, on their wedding day as they converse with members of the royal family, including Queen Elizabeth II.

The photos, captured by the late Lord Patrick Lichfield at Buckingham Palace, will be sold by RR Auctions on Sept. 24 at the Royal Sonesta Hotel in Cambridge, Mass.
