I’m going to call this out and say this looks like a corporate stunt, looking to mooch publicity off of the “controversy” of “street art” (all quotes specifically intended).
I personally approve of making dough off of anything. Especially street art. Co-opt to the max. But I’m also pretty broke and would just like the money.
[ed. note- just realized this is outside a gallery in Paris. Same thing, all of the above still applies.]
