So, it just so happens that I found some stolen art in a friend's storage unit, while helping sort through stuff to sell on ebay. His grandfather died and he has to get rid of all the stuff.
At one point, years ago, the grandfather told me about this art. He was a Marine who stole it from the Argentinian embassy. Right off the walls. By my math, this would have happened in about '68 - '70.
I asked if I could keep the pieces of art, because they don't look like much.
So, they are still sitting in the storage unit and I can pick them up at my leisure, or not. I remember being able to find something on the Internet about it, when I was first told the story, but I can't seem to relocate any of the details.
Have stolen art. What do? Return it to embassy? Sell it? Keep it? Forget it exists?
