I've got an actual poster, although it's a bit tatty now (got it when I was around 16/17 before I'd even heard of the KLF) - I think you can still pick 'em up in places like Athena...
does Athena still exist? all the ones round my way closed up years ago
tis a cracking poster though - i put it up on the wall again when i first heard the LotR films where gonna be made
