This is by Nadia Plesner. She used it as a t-shirt to raise money for the victims of the Darfur massacre.
So Louis Vuitton sued her.
Now she's used the image again, and they're suing her for unlimited damages again, despite the image's status as art ('fair use') and non-profit.
Could it be that they're embarrassed by the juxtaposition of enormous and self-indulgent wealth with real suffering, and want to silence anyone who makes the connection? I think it could…
What can you do? Well, do as I do: boycott Vuitton goods (not, I admit, a difficult struggle) and send the Red Cross some money.
