Few people outside of its host nation are aware of it, despite it being hailed as one of the rarest art treasure troves in the world.
Masterworks by artists like Jackson Pollock, Andy Warhol, Pablo Picasso, and Vincent Van Gogh have been mysteriously stored in the basement of a museum in Tehran, the capital of Iran, for many years.
In 2018, estimates put the collection’s value at up to $3 billion.
Since the Iranian Revolution of 1979, only a small percentage of the work has been on display, but in recent years, the Tehran Museum of Contemporary Art has been displaying some of its most striking pieces.
