Pretty authentic-looking, and all around $1000. Not cheap, no, but the real thing is upwards of $10K.
Here's the question: with something so identifiable, would you ever be happy with a knock off? I myself have authentic Ghost chairs and vintage eames fiberglass shell chairs, knock-offs for both of which are now readily available, so perhaps I am something of a purist? At the same time, I have a giant Noguchi-style lantern in the dining room, which I will readily admit is from PB Teen.
If you are into modern design but not so into the price tag, and you are down with the whole knock-off thing, France & Son has many, many items you might like to see.
