A painting by Vincent van Gogh will be sold at auction after 30 years.
The 1887 painting Les canots amarrés will be offered for sale by Christie's Hong Kong on September 26 and has an estimate of $30 million to $50 million.
The painting was part of the collection of the Bourbon-Two Sicilies royal family, descendants of the historical rulers of Sicily and southern Italy.
It was then bought by Italian actress Edi Wessel from Sotheby's London in 1991.
The work is part of the landscapes that the Dutch artist painted in Annier-sur-Seine during his travels in France.
