Well, thank you very much. I'm not sure about how original my technique is here, but okay. I just solved the problem the best way I knew how.
I used to work on staff in the Warner Bros Consumer Products art department. As part of WB Marketing, we provided style guide art for licensees around the world for use on their merchandise. With most of the basic line art and design produced by WB's own in-house artists, a standard of quality was better ensured as exclusive images filtered out to the public on toy packages, apparel, and accessories.
