I don't know about the printing on the cassette, but all the items that you've mentioned come from the Canadian vinyl release of DSOTM. All that you're missing is another of the stickers, as all original releases came with the pyramids poster (only green in Canada, blue certainly in Europe), the live poster and the 2 stickers. None of this is very rare and without the original album or the other sticker, good only for looking at.

I think that this was mentioned in another forum, incidentally.

Cheers,

Mark
