An interesting detail is the substitute Lisa system font.

(I'd conclude, this is either a handmade drawing, or a screenshot of a prototype before Apple settled on the final font. Maybe used as a comparison showing off the use of bitmapped images on the Star, something not available on the Lisa? And/or, as indicated by another comment, comparing screen sizes?)

Also, mind the slight angle at the top edge, where the screen content and the monitor meet. I guess, this is not a screenshot but a montage.

The screenshot seems to be based on one from a Lisa brochure here: https://archive.org/details/AppleLisaBrochure/page/n12/mode/... (page 13 if link doesn't go to the right page, the LisaProject example). Seems to be some sort of remake as beyond the brochure example being very low res things like text spacing are different (circles cutting off bits of text inside them is obvious one on the Alto shot).

Great detective work!
