I ran into quite a few NYC Urban Sketchers in the closed off gym. They were busy with the nudes and talking about lunch.

Drawn on a long folder from an auction house, painted with black and white gesso (=gray). Panels a-d drawn with pencil, then Sharpie fine pen. Pencil, poorly erased, interfered with the flesh color.

Colors were Caran d’Ache Neocolor II with water brush on location. White is acrylic and black is gesso – added at home. Background is totally make believe fiction.
