I did a Google Image search for "Hunter Biden art." I thought some of those paintings were pretty good. Not $500K good, but not bad, either. And like you, I wonder who is painting them, and of course its a money laundering operation.
Not entirely unlike Hillary's "What Happened." I bought it, and read as much of it as I could stand. It was AWFUL, as if it was the diary of a self-absorbed teenager. I hope she didn't write it, and in addition, I'm pretty sure she didn't read it. I'd bet most of the sales were "pre-sales" to various outlets. Money laundering is where it's at.
Even HUMA ABEDIN wants her cut of the money with an upcoming memoir, ROFL.
