Just out of curiosity, are any of them autographed? You seemed to have met a few people and all.
H.M. the Queen doesn't do autographs, no way.
The first photograph I ever got was the official Canadian photograph of H.M. the Queen, 1976; the usual and standard photograph that hung in governmental buildings at the time.
Then I got the official Australian photograph of H.M. the Queen, taken a year earlier than that, in 1975, the usual and standard photograph that hung in governmental buildings at the time.
New Zealand was a pain, because at the time (late 1970s, early 1980s), New Zealand didn't have an official photograph, but I finally found the official photograph as used by the Royal New Zealand Navy, courtesy those guys.
And then there's one that hung in the governmental buildings of Mauritius and Jamaica.
They're all different, of course, but dating from 1976 to 1983.
But seriously, no; H.M. the Queen autographs for no one. Her and the Pope.
