I am expanding my collection of cylinder seals, however I am at a loss
of where to find more.  Right now I am aware of E-bay, and
http://www.medusa-art.com/ as being two very fine sources, however I
would like to know where else I can get access to auctions, stores,
or private individuals that are selling their collections or findings.
 I am most specifically interested in the Near East cylinder seals
from at least 500 BCE if not long before (2,000-1,000 BCE and earlier).
