These guys were from photos found online. Usually I only have time for a few drawings, just enough to loosen up, before I have to start working on something "real" (meaning with a deadline and what pays the bills :)
And now I want to encourage everyone who hasn't already done so, to get the new collection of Harry Bush artwork "Hard Boys". I just got my copy yesterday and it is GLORIOUS! I love the care that went into reproducing his delicate shading...often you can even see the patches and taped over areas of the drawings where Harry would constantly revise his art. The bio info is also well put together. It's sad to read that someone with such beautiful artwork was unhappy in his daily life. He reminds me a little of ol' Alex Toth in his seclusion and grumpy correspondence.
Buy this book or put it on your Christmas list...you will not be disappointed!
