Provenance puzzle #2 -- solved!
I have two people to thank for independently solving my Provenance Puzzle #2: my friend the San Antonio tax attorney and bibliophile Farley Katz, and Christopher Frey of Antiquariat Inlibris Gilhofer in Vienna.
The armorial stamp, shown at left, is of the Austrian nobleman Joseph Anton von der Halden (1665-1728) from Vorarlberg, who was
created Baron in 1686. The letters around the border of the stamp, "I A E V D H F Z A H Z A V O", stand for
"Ioseph Anton Eusebius von der Halden Freiherr zu Authenried Herr zu
Anhofen und Ochsenbrunn."
This stamp is found on fourteen folio volumes that came to the Lillian Goldman Law Library as part of the Roman-Canon Law Collection of the Association of the Bar of the City of New York. They are all bound in stamped pigskin over wooden boards with rounded spines.
Farley Katz provided his solution via the wonderful Can You Help? website sponsored by the Consortium of European Research Libraries (CERL) and operated by Dr. David Shaw. It enables users to post images and descriptive information for bookplates, armorial stamps, and other provenance evidence that they cannot identify, in the hopes that others can provide answers. It's crowd-sourcing for provenance research. Farley's solution to Provenance Puzzle #2 can be found here.
Christopher Frey provided an additional source for von der Halden: Alexander Schneder, "Die Von der Halden in Vorarlberg. Eine genealogische Studie", in Jahrbuch der Heraldisch-Genealogischen Gesellschaft 'Adler', Jg. 1951/54, Folge 3, vol. 3 (Vienna 1954), p. 30-43.
Quoting from Frey's email to me: "We once had a set with these exact armorial stamps - Leibniz's Codex juris gentium diplomaticus (Hannover, 1693), which later ended up in the library of King Ernst August I of Hanover (1771-1851). King George V of Hanover later presented the set to the historian Onno Klopp, who followed the King into exile to Vienna. The set then turned up in the library of the Vienna Discalced Augustinians, from where we acquired it." It turns out that Frey's firm sold this set to our next-door neighbors, the Beinecke Rare Book and Manuscript Library.
Additional help came from Susan L'Engle of the Vatican Film Library, St. Louis University, and from Klaus Graf.
