found you the way anyone finds anything these days -- Google.
I have previously seen some Golden Age comics on Usenet (a.b.p.comics) -- there seems to be some overlap with what is posted here, I suspect they were reposts of what's in your archive, though I don't recall having seen a link.
My interests are "mid-century illustration" generally, and editorial cartooning back to the 19th century -- it was Gillray and Joseph Keppler (of "Puck") who first excited my interest.
Of Golden Age material, I'm least interested in superheroes (except really odd ones, like those of Fletcher Hanks), and more interested in social and editorial commentary.
