Earl Grenville Killeen included my work as one of 20 artists illustrated different approaches to the use of acrylic in his book, The North Light Book of Acrylic Painting Techniques, authored for North Light Books, in 1995. I thought that it was out of print years ago because North Light took it off their active list. However, I recently located it, reissued in 1998 and for sale on Amazon.com. You can order this book, new ($17.99) or used (from $7.37 -- but watch out for the shipping costs before you hit the order button) at Amazon.
In this book, he includes 20 different artists, illustrating 20 different approaches to the use of Acrylics. It's very instructive for those artists approaching the use of the acrylic medium as it gives you an overview of some of the very different ways to handle this medium.
