I have a German copy of CMI which came with a nice manual PDF:

It seems to be stored as a JPG but with some weird colourspace, so here's a PNG version copy/pasted out of a PDF viewer.
There's also a surprisingly hi-res version of the Monkey Island picture from the opening FMV, but the PNG's too big to attach here.
