Pinakos, owned by Rudolph Heinemann, is a name that pops up in Nazi-looted art and false provenances.
However, the Pinakos name has a tendency to be scrubbed from provenance records, replaced either by its owner, Heinemann, or, occasionally, its frequent partner, Knoedler.
This is a pity because while Heinemann and Knoedler operated over long periods of time, including long before WWII, Pinakos is a name that appears only at very specific times. (So specific that it can be used to date undated ledger entrees.)
Pinakos Inc is rarely found alone in the Knoedler ledgers. Usually it appears as a "joint owner". An interesting pattern is Pinakos as first a "joint owner" and then, without the other partner, a seller in a separate ledger entree.
Pinakos Inc often appears in leger entrees "carried forward". Some transactions involve exchanges or returns with several different Knoedler numbers.
This post examines "joint owners" which appear in the Knoedler ledgers together with Pinakos.
