Thanks to an anonymous commenter in the previous posting here, I learned that Andrew Loomis's landmark art instruction book Creative Illustration is going to be reprinted this coming September in paperback. On Amazon.com, the price is an amazingly low $13.57. I'm curious to see if the reprint will include the colour pages, but even if the book is not complete (and at 300 pages I'm guessing that it is), this is a major bargain as well as a major event. If you draw or are interested in drawing, this is easily one of the best art instruction books ever published.
Update: Lars asked in the comments what it was about Loomis that made him so great. I find his art very appealing. In addition, he is excellent at communicating artistic principles through his diagrams, drawings and text.
Creative Illustration is broken into the following sections: Line, Tone, Color, Telling the Story, Creating Ideas, Fields of Illustration and Experiment and Study. Below are some pages from the book that I hope will give you a taste of Loomis's skill and approach.
