This old book has some strange printing problems. Some pages are damaged with crumpling but there are gaps near the crumbling which I believe indicates that the paper was crumpled during printing. I made two edits, one with an attempt to correct the crumpling and close the gabs and others minimally editing showing the gabs and strange printing. Other pages have a kind of shadowing which seems like some ink didn't line up with the other ink. I'm not sure if this is the case or if the author intended this effect so I also provided two edits, one with the shadowing removed and others with the shadowing on the page. Finally, I also provided minimally and extensive edits to the front and back covers.

This is older than the first Comiket.

1974. One of the oldest books scanned here. Nice!

But for the edits, I'd recommend just uploading two different galleries
