This is an official compilation of parts 4, 5 and 6. Parts 1, 2 and 3 are in the second official compilation. Neither of them contains the + book (/g/235078/b0658c978b/) Also included in this release are covers for + , and I have no idea what the last two pages are (alt pages for part 2?)
Individual, older galleries: * 4: /g/242063/31e6e5e38d/ * 5: /g/71755/0635aa1617/ * F: I don't think we have it in the gallery yet See first official compilations for links to 1, 2 and 3.
Oh, + I think goes between 3 and 4. No idea why it wasn't included in one of the official compilations...
