Hmm, now that you mentioned it I remembered the different cover. Looking quickly across the net it seems that the cover shown above is the first one because it is sold variously with promo stickers on back and front. One seller refers to the other cover (posted at discogs) with the remark "2nd cover". What is more, my copy has the red labels (with eye) I uploaded above, whereas the LPs with the different cover show the red labels with yellow Columbia rim print and without eye; this latter one was used only from 1970 onwards, as far as I know, so this again points to the fact that the other cover came second. Let's hope W.B.lbl soon comes across this comment to settle the question :))
P.S. I really hate the red Columbia labels with black print coming out this bad and fuzzy when scanned !! I don't know how to amend this.
My copy also has this front cover, but Discogs has a different one, which was reproduced in the British 2-on-1 CD some years back. Any idea which one came first?
