Just google, Renoir's "Gabrielle Avec La Chemise Ouverte". It's not in Tehran!
This painting was such a treasured piece of the TMCA that in Feb 23, 2003 it was excluded in a special request to the Iranian Parliament to sell 10 to 20 'Western" paintings to raise money to buy more Iranian works. By the way, this motion was defeated by the people. The collection is that important to the people of Iran.
Over the years, the explanation of the TMCA officials why the Renoir was never shown is because "Gabrielle's blouse is open" but the real reason is she is no longer there. Gone!
Originally, the TMCA had an open web site with 151 paintings and 24 sculptures before this recent "sitting" President took office. Once it was taken down, it appears that many pieces have disappeared out the back door. Derain's "L'Age D'Or" original is in New York City in the hands of a private collector while Jasper Johns' "Decoy I", "Decoy II" and "Pinion" are elsewhere as well. There are approximately ten pieces in question.
The TMCA collection was valued at $3 billion.
The "Mullah Mafia" has stolen and transferred overseas over $100 billion in other assets out of Iran. There is no doubt that the Tehran Museum has also been a victim.
