Works from Iran's long-hidden collection of modern art may soon begin to travel. Officials in Tehran are negotiating a loan fee of up to $3m with their German counterparts, reports The Art Newspaper. The fee is for Berlin State Museums to host an exhibition of works of modern art from the collection of the Tehran Museum of Contemporary Art (TMoCA).

Rome’s museum of modern art, MaXXI, and the Hirshhorn in DC are also said to be interested in loans from the over $3-billion collection. The Tehran museum was established by Shah Mohammad Reza Pahlavi’s wife, Farah Pavlavi, and most of the collection has been in storage since the Islamic Revolution in 1979. The museum reopened in Nov. 2015.
