I don't know if you're joking or not, but you're willing to throw 18k away for a poster paper?
I would at least invest the money or get a car, but that's just me.
To each his own man. People drop thousands on a pair of kicks. Millions on paintings of soup cans. If I had $30k to blow on this I would, but I dont. The auction says the whole thing is 34x57inches.. Get a tape measurer. Thats insane. My boy bought a set of 2 Kaws Companion prints. One pink and one gray around 13x6inces each. He paid $7,000.00 for the pair! You can fit like 30 of them prints he bought in this piece. I can buy a car any day of every year for the rest of my life, but stuff like this I might not see again. But unless I can barrow money, I doubt I will be the winning bidder.
