This work was recorded as “unmounted” in the paperwork documenting its sale from Marlborough Gallery, Inc., New York, to Allgemeine Europäische Kunstanstalt, Liechtenstein, via Galerie Stutz, Pulver & Co., Vaduz, Liechtenstein, on June 28, 1971. It is believed, though, that it was mounted by Marlborough Gallery conservators Edward Brown and Alan Thielker.
