Five previously unseen photos of a young John F Kennedy are to auction.
The snaps feature the future president as a lighthearted teenager in the early to mid-1930s.
The five photos are estimated to make $2,000 when they sell as a single lot at RR Auction on September 16.
The Kennedy family gave them to biographer Gene Schoor in 1961 while he was writing his book Young John Kennedy.
A 1935 photo of Kennedy in high school graduation cap and gown is among the items. Kennedy attended the prestigious Choate school in Connecticut.
Another photo features Kennedy and a roommate in a drama club rehearsal, while a third depicts Kennedy horsing around with a group of friends.
"An absolutely outstanding, one-of-a-kind collection of original material from Kennedy's formative years," commented RR Auction's Bobby Livingston.
"We've seen JFK at Choate - but you don't really see images like this. The one outside his house with him and all his buddies [below] - that's what he was known for. Jack as a young person was always thought of as a cut-up.'
"He was mischievous at Choate. Joe, his father, didn't see him as the presidential candidate. That was his older brother, Joe Jr. So he's relaxed in these pictures."
Kennedy memorabilia routinely auctions for large amounts. A pair of flags that stood in the White House's Oval Office during his time as president sold for $425,000 in 2013.
