The picture above is not a Kara Walker. It's a Katharine Wolkoff commissioned portrait. If you look closely around the neck you might be able to see that it's actually a color photograph. Katharine devised the complex lighting set-up for these silhouette portraits a few years ago and they have since been acquired by museums and collectors. She does her own printing - a rarity these days - and her prints are stunning.
A 2002 Yale MFA graduate, Katharine refuses to be pigeonholed and her two latest projects were a look at post-Katrina New Orleans in the context of the Southern landscape, and a special issue of 2wice Magazine where she photographed the Merce Cunningham Dance Company in the grounds of the historic Vizcaya estate in Miami.
