Windows/386 2.03.06 (Toshiba OEM)

BetaArchive user TheCollector1988 found an bootscreen screenshot of Windows/386 2.03.06 produced by Toshiba on Facebook. It is unclear if this is a pre-release version of Windows/386 2.03 (due the '06'-part) or this is referring to Toshiba's own version numbering-system.
