Here, on the occasion of the 60th anniversary of Elizabeth II’s reign, LIFE.com offers a series of informal portraits of the Queen, including several that never ran in the magazine. And while some of these images do convey “oodles of symbolic supremacy,” it’s also worth noting that, in at least a few of these shots, there’s also a flicker of something that one hardly ever associates with Elizabeth: namely, a quite self-aware and yet wry sense of fun.
