It's signed, and the estate has agreed to issue a certificate of authenticity. So maybe this 2" x 42" painting of a row of radiant babies didn't get a single bid at auction today because all the merchandise licensing agreements have already saturated the Keith Haring wallpaper border market.
That said, if you really want it, you should contact Phillips de Pury; I suspect they have a motivated seller.
