As I was poking around the Internet Archive of digital books, I came across an amazing find: An 1877 BEP specimen book with about 100 proofs of bureau portraits and vignettes. Dozens of these engravings can be found on U.S. currency of the time -- Nationals, Demand Notes, Gold Certificates -- it's a fascinating collection. I posted just a few here, as a teaser. This particular book was specially bound for Richard W. Thompson, who at that time was the newly appointed Secretary of the Navy. If you are at all interested in the art of Bureau engravings, you'll want to scroll through this digital wish book. Click and zoom on each image to get a close look. https://archive.org/stream/specimens00unit#page/n29/mode/thumb
