He was born in Hawaii where he spent most of his life, becoming a key member of the so-called Volcano School - the group of non-native Hawaiian artists who painted dramatic nocturnal scenes of Hawaii’s erupting volcanoes.
This 8 x 10in (19 x 25cm) work, depicting two figures enjoying the waters of a tropical riverbank, probably dates from the 1920s when Hitchcock’s style had become more impressionistic.
At the time he was exhibiting regularly at a series of commercial galleries in Los Angeles and San Francisco in particular.
His work can bring substantial sums so this one, miscatalogued and estimated at just €100-150, was doubtless something of a bargain at €2000 (£1740).
