Yes but the Hyman citation is just too good, even compared with the Lehman. The fonts look too different for the era. How was this produced in 1969? Yes I know he may had it replaced but that is why we see a Lehman citation.
By the time we get into the period of photo engraving all things were possible.
We went from plate printing to offset litho circa 1973/74 due to some serious price changes for doing medium size jobs (USPS forms for use by the public ~ 100,000 to 250,000 copies per replenishment).
The composition costs actually went up. Reproduction costs went down. By 1979 I was able to get a complete DMM printed on newsprint for 75 cents a copy in quantities of 175,000. The Federal Register cost more because they had tighter deadlines (daily rather than semi-annually for a total production).
You should see the justified stuff we did back in the 1960s ~ it was great. Newspapers were a bit sloppy, but they used hot type.
