I came across an artist, Dave B. Tibbetts, a fly fisherman who paints watercolors on fly fishing. You can read this article on him, Zen and the Art of Fly Fishing, by Robert Dixon. Interesting story on the artist's life, shows a selection of his paintings of fly fishermen.
Tibbetts is up there in years but certainly going strong (inspiring in itself). Sounds like a modern day Winslow Homer the way he combined painting with his love of hunting sports and outdoor life. Of course Homer didn't do commissions, didn't have to. But then he was at another point in the art history continuum. He came along when photography and (the industrial revolution) were gaining momentum. Art was developing a different purpose. Homer was one of few watercolorists, in a field that had not yet been developed. There was not a broad middle class yet, a broad market for this kind of commission work (paintings of homes, favorite spots, etc.). The new world of watercolors was then wide open for such a master draftsman and brush handler as Homer. He made his place at the head of America's foremost watercolorists, along with a few others. The Tibbetts story is intriguing and inspiring because of how he's joined his two loves, painting and fishing.
I am working on some coloring pages, of fish and fishing, based on the art of Winslow Homer. I'll put them up soon. Meanwhile, here is my pen and ink drawing, of bears fishing, for you to color. (Click title link for enlargement.)
