A photo marked "not to be published" that shows a teenage Diana Spencer before she became Princess of Wales has sold at auction for more than $18,000.

Photo of teenage Princess Diana released

The photograph shows Diana reclining on a bed, with a young man seated behind her and a bottle of whiskey on the windowsill. British media reports said the photo was possibly taken during a ski trip around 1979 or 1980, when the future princess would have been 18 or 19 years old.

It was acquired by a British newspaper just after her engagement Prince Charles in 1981, but someone at the paper wrote "not to be published" across it, presumably because it would've embarrassed the royal family.

RR Auction in Amherst, N.H., says the photo sold in the online auction Thursday to a real estate investor from San Diego for $18,306, well above early estimates.
