Many Amaz0ns readers are surely familiar with Joseph Michael Linsner, who has been writing and drawing "Dawn" comics for almost 20 years. Linsner produced a "Not Dawn" sketchbook this year - just 1000 of them - and several are available over at eBay. I mention it because there are at least two Power Girl sketches within.
While Linsner is one of several popular American comic book artists known for a lush, sexy style of drawing women, he is somewhat unique among his peers in that he has done almost no work for the major publishing firms, DC and Marvel. Instead he has chosen to work mostly on his own characters in storylines that (to me, at least) long ago became repetitive and uninteresting. Still, the art is great.
