Okay, on all three of my copies, the A side is "The Pictures On My Wall." The B side is "Read It In Books."
On both the lighter blue and darker blue striped copies:
(A Side) The runoff is etched with: CAGE 004-A, LYN 6542-IM, MAX
(B Side) The runoff is etched with: CAGE 004-B, THE REVENGE OF VOODOO BILLY, LYN 6543-IM, MAX
On the silver/black (reissue) copy:
(A Side) The runoff is etched with: CAGE 004-A-1, *MT* L (note: the 4 is written over a 6)
(B Side) The runoff is etched with: CAGE 004-B+, *MT ankh symbol
I agree with tomo that the sleeves on the non-reissue copies have a stronger red and more defined design. However, the Balfe, Drummond reference is present only on the sleeve of the reissue copy, not on the others.
The mystery continues....
