Gutenberg is the original source of the article PDF, which is generated from a modern text-based source, and is not a scan of the original.
I find original typography (and sometimes incidental notes and markings) interesting. Archive.org does have a source scan from the Library of Congress:
A few notes on the different versions. The Archive version is a scan of the printed version. The scans are OCR'd to make it somewhat searchable, but the large filesize reflects the fact that it contains text scans. The Project Gutenberg and GITenberg versions derive from proofread and corrected text produced by Distributed Proofreaders. ( https://pgdp.org/ ) The GITenberg PDF is a conversion from EPUB by xvfb.
