I, too, bought a copy in 1978 for $80. I don't recall it having a poster, but it was in otherwise in nice shape. I mentioned paying $80 for it to Jan a couple years later and he seemed surprised. I can't imagine anyone doing a resissue or a bootleg on it back then, at least not putting that much effort into making it look like an original. But, I could be wrong. The album was less than 20 years old at the time, so it's plausible that some nice copies were still floating around.
