This painting is the most expensive artwork ever auctioned in human history,
without exception.
The most recent market transaction saw it bought by a Middle East prince for nearly five billion dollars, a sum higher than the market value of most medium-sized listed companies.
"Savior" is indeed a fine painting.
But to this day, the true identity of the painter remains shrouded in mist and doubt.
Some believe this painting was Leonardo da Vinci's last completed work.
Others believe it is the masterpiece of Leonardo da Vinci's student, Bernardino Luini.
Some even think the author is a representative of the later Milan School, Botafio, or perhaps some other painter who left no name in history.
A master-level artwork with exquisite brushwork, yet the specific author is unknown.
Such a situation wouldn't only be encountered by Gu Weijing and his peers.
The situation of "Savior" is very similar to the problem that Koizumi Katsuko and Gu Weijing need to handle.
