It's in my parents house somewhere. Don't know if it was official, but there was another site I went on last year, that posted a scan of the info. It definetly said that Stormtroopers were clones. But they could have just got the info wrong.
I'll have a look for it next time I go round!

Actually some here might have it. It was a poster magazine, and one one side was a poster of Han, Leia, Chewie and 3PO in the falcons cockpit. On the other side was a load of info about the Empire. This months was the Empire month. I think there was a set of 3. Anyway, the older fan here still might have theirs.
