First this Thomas Balmer plate engraved by
Next this plate belonging to Madge Carr Cook (an actress with a few Broadway credits around 1900) . This one is signed. Looks like "H. Badirian 19XX" but is way too tiny to make out. Found in History of Frederick the II (Chapman 1859)
This one belonging to Leoh Waldman is perhaps the strangest I've encountered. It features an Ostrich with a globe body hiding its head while a horse in a checkered jockstrap looks on smugly. Found (appropriately) in Freud's Psychopathology of Everyday Life (Macmillan 1920).
These last two plates belonging to and designed by George Gates Raddin, Jr., historian and bibliographer, were both found in The Bedouins by Huneker (Scribner's 1922).
The first plate was on top:
pasted over this one (which is the first bookplate I've encountered that should be labeled NWS).
I wonder if Mr. Raddin became ashamed of his "money shot" design or if he suddenly became more besotted with Rockwell Kent than Aubrey Beardsley.
