This interesting looking model has appeared several times in The New Yorker:

Everything I do tends towards caricature, even my "serious" drawings.  I exaggerate features any time I draw or sketch.

This next woman came out of one of those magazines that are made up entirely of avant garde advertisements.  I think it was probably Vogue.  My youngest sister, who is also an artist (http://www.bluecanvas.com/stacree) is generous with her used reference material and shares her old magazines with me.

I don't like to do a lot of smearing when I draw so I adopt inking techniques (hatching, cross hatching) even when I use pencil.
