Jim and Ruth Keegan are the creators of The Adventures of Two-Gun Bob, which appears in various Dark Horse comic books. They've also illustrated a bunch of prose books and dust jackets. Their work has appeared in several Spectrum annuals, and has been exhibited at The Society of Illustrators in New York.
Here's a few more examples of our B&W ink-wash work. These were all painted with an inexpensive Loew-Cornell #6 on 10 × 15" pieces of cold-press illustration board, using Higgins non-waterproof black ink (& water).
