"Nikki" by Les Toil (from http://www.toilgirls.com/pinups/nikki.html)
Les Toil is a graphic artist who features bold, confident and whimsical pin-up images of large women. (Note: many pictures in his gallery are NSFW) Actual large women, as in portraits! It's fascinating to go through his gallery and see a photo of the actual model alongside the piece. He tries to capture her personality in the setting, not just her body. You can get your own portrait created ($$$!) or just peruse his pin-ups for a mood boost.
His work should be familiar to those in the FA community, as he's designed promotional posters for the dance company Big Moves and Logo/advertising art for a range of Fat-positive companies such as BBW Travel, Chicago BBW, and Torrid. He's also the artist behind the graphic novel "Shmobots".
