I don't know about the cover, I'm afraid, Alice was never my thing! That site would be right about the grey labels being the third pressing, as Discogs has a copy with the mid-70's Burbank labels (but without any label images to confirm it).
Thanks for your comments PhilMH. The web site alicecoopercollection.com suggests that my copy is an Australian 3rd pressing from 1980. So, did all Australian vinyl pressings continue to use the infamous "Thumb" cover uncencored?
Whassup's green label copy looks like an original, as the WEA Records Pty. Limited name didn't come into use until 1972. MoreFloyd's grey labels are from the period mid-1978 to early 1984.
Added slightly different back cover (bottom right corner - Distributed by WEA Records Pty. Limited. A Warner Communications Company) and different labels to Whassup's initial images. Front "Thumb" cover is exactly the same. I think my copy might be a later re-issue but there is no date anywhere on labels or cover. This is my favourite Cooper album.
Hey Whassup and wax_museum, I haven't seen this one for a while and I'd rank this and Killer as two of Alice Cooper's best ever efforts. I don't own either but if I were to buy any Alice Cooper albums (I have none) that's what I'd buy.
