I was seven and a half when Armstrong took that step. Even in the UK all the boys were collecting soup-tin labels (I think that was what the promotion was on?) during the Apollo program, so that we could pester our parents to order the "free" posters of some of the amazing photographs. I think I recall reading recently that a moon-mapping satellite had seen the shadows from the equipment left on the moon surface, and that the flag was still standing. Possibly that was another of the landing sites though.
(Edit: I eventually checked this. The sites of Apollo's 12, 16 and 17 still have their flags. The Apollo 11 flag was seen to blow over in the blast as the module took off, so the later astronauts simply placed the flags further away).
Thanks to RichW, above, for the link to the transparencies and other photo materials. It gives a new meaning to "Sunny-16" (yes, I know that wouldn't actually work very well without an atmosphere) and it was reassuring to see that there are a couple of accidental exposures of hands and elbows in the collection!
For seven year old me, I can certainly admit that Armstrong, Aldrin and Collins inspired a lot of enthusiasm for science and technology.
