I got my MFA in 1988 and don't recall much if anything about the technique. I really found out about it reading a book about it at "Borders Books" of all places. This was 1999. I searched through my library and I have a great book called Space Capsule by Michael Becotte. It clearly is all done with lith printing. The date is 1975. "American Images; photography 1945-1980" Pete Turner, No clear lith images. "A critical history of American Photography" by Jonathan Green has no clear lith images. He does reporduce a Michael Becotte image (1974), but the reproduction does not show the lith character. I checked Beaumont Newhall and there is no reference to the technique. It does show a 1971 Les Krims "Homage to the Crosstar Filter" that looks like the lith printing technique. There is a self portriat by Bruce Nauman dated 1970 that could be lith printing. If so this would be the earliest I have found. Here is a reproduction on the web: http://www.telegraph.co.uk/arts/graphics/slideshows/nauman/b8.jpg Anyone know anything more?
