I often see catalogues from auction houses that have tons of famous
jewelry for sale. The two big houses are Christies and Sotheby in
NYC. They have all the back issues. These can be found in book
stores, also.
Happy hunting. June
If this is some type of educational project, you should question the
party directing the project as to how to obtain catalogs. To me, your
request is quite vague, leading me to believe that underlying motives
are in play here.
