TIME Magazine obtained and published this picture of President Obama the night of his senior prom in Honolulu, Hawaii, in 1979, from his classmate Kelli Allman.
From TIME's press release on the picture:
Pictured left to right in the attached photo: Greg Orme (Allman's date and Obama's friend), Allman, Obama and Obama's date Megan Hughes.
TIME is also releasing a note Obama wrote in Allman's yearbook at the end of his senior year that reads, in part, "You are extremely sweet and foxy, I don't know why Greg would want to spend any time with me at all! You really deserve better than clowns like us; you even laugh at my jokes!"
