As well with this Led Zeppelin 2 is "THE LEMON SONG" To be on this vinyl or another song?

So you would say these are all fake signatures, and the drawing as well even though it's like the zeppelin blimp on the other vinyl cover.

OK thankyou, signatures do look real cause there names are missing off the sleeve. As for the drawing it may or may not be the same blue pen. Would like to know a little more why Robert Plant and John were not printed.
