Obama, rocking a white blazer and a blue tie to match date Megan Hughes' dress, had a "pretty typical" prom experience, according to Allman.
"It was a really fun, happy time. We were all cracking up, and everyone was smiling," Allman, who was dating Obama's basketball player friend Greg Orme at the time, told the magazine. "It was pretty typical from there out as far as what happens at prom: the dinner and the dancing and the photos."
The photos were published along with Obama's signature in Allman's yearbook.
The POTUS was quite the charmer in his note, offering to take Kelli "out for lunch sometime" and calling her "sweet and foxy."
According to Time:
"Barry spent his days at the Punahou School in Hawaii studying, shooting hoops and goofing off with his friends. Greg Orme, a fellow varsity basketball player, was Obama’s constant companion. “They were like brothers,” says Allman. On prom night, the pair double-dated. Obama and his date Megan Hughes, a student at the Hawaii School for Girls at La Pietra, joined Orme at Allman’s house, where the two couples sipped champagne before going to the dance and then an after-party."
"Tucked away in someone else’s shoe box of adolescent artifacts, there might be a picture of you in garish clothes and with an outdated ‘do, your arm around a high school squeeze. The President of the United States is no different. These previously unpublished photos, obtained exclusively by TIME from Obama’s schoolmate Kelli Allman (née McCormack), show a 17-year-old Barack Obama on the night of his senior prom."
