Bob Dylan's Greatest Hits Sleeve Variant

Hi,
I have a sealed copy of BobDylan's Greatest Hits KCS-9463. I've narrowed it down to either a 1967 or 1970 release. The hype sticker is on the front, the poster is inside the shrink wrap, rather than inside the sleeve. I'm not sure if that was the way all the posters were included. The shrink wrap does have the "breathing holes", so I don't believe it was resealed. Due to the fact that the poster is on the outside of the back cover (inside the shrink), I can't get much of an idea where it may have been pressed. There are indicators on some of the back sleeves. The one thing it does have is the number "6" on the back of the sleeve, bottom right corner, to the left of the Columbia logo. I know the number is correlated to where the sleeve was printed. I've found copies with the number "1" and the letter "A" in the same location. They were on first presses and represses, so after typing all of this, I realize the number "6" may not even help to determine if I have a 1967 or a 1970 copy. Thanks in advance for any help anyone can provide. I'll take a few pics and try to attach them to this post.

Interesting that the poster is outside of the album jacket!
