By doing away with the inquiries-only model, the new click-to-buy online marketplace Platform makes acquiring high-end art easy and transparent — you don't even need to be a collector, much less a VIP, to shop it (interior designers take note!). Backed by David Zwirner gallery, it offers 100 original works each month, by artists ranging from Lily Stockman to Erin O'Keefe to Kalup Linzy, at prices ranging from $1,500 to $50,000 — and if you win this giveaway, you could have one of them hanging in your living room.
