The image of Prince Philip, Duke of Edinburgh, that we're all used to pretty much goes as follows: he's in a nice suit, or maybe one of his official military dress uniforms, walking just beside or just behind Queen Elizabeth II, either grinning at some private joke or looking a bit frustrated to be there. Although he's retired from public life now, the Duke of Edinburgh [1] has spent nearly his entire adult life (and much of his childhood [2]) in the public eye, which means there are no shortage of images of him [3] out there. In celebration of his upcoming 98th birthday on June 10, we've dug into the archives for 25 pictures of Prince Philip you might not have seen before — but you'll be glad you did!
