This piece is being sold on behalf of a third party, who purchased it in an auction in America.
Guruve have tracked down the gallery that bought it from Joseph, so there is now proper provenance for this piece, including the gallery's sale receipt and the original photograph from 1986!
It is unmistakeably an original 'Joseph', and his signature is deeply etched into the side.
The stone is a mixture of red and green serpentine that was used by some of Zimbabwe's top sculptors in previous decades but is no longer available, adding to its authenticity.
The piece is now in the UK and will be shipped from there.
