Unless I have missed some, this is the last of the Julius Zimmerman works collected from Naughtybids. As detailed in a note on the ZimmermanArtArchives @ Google Groups, Julius Zimmerman passed from this world on November 8, 2017.
The only works that might show up now would be commissions that individuals received that they might decide to release. Quite an archive, though. Almost 17000 items just offered on Naughtybids alone.
