This is a weirdass Mario book called, presumably, "The Mario's Dream Upside Down World" written by two people who are daring enough to have their names on the front cover. "Illustrated" is used in the loosest sense here, I recommend "haphazardly traced"
Unluckily, Peach gets hurted.
the Bros's finger count is weirdly consistent though Peach gets five fingers
(I originally found it off this imgur by "SurgioClemente" but I reuploaded in case the image gets broken)
