In the same vein as Charley Harper, Etsy seller beethings makes some fun and cheerful prints featuring graphic interpretations of various bird species. A great example of affordable art, any of their prints would quickly and easily brighten up a room.
And in addition to their shop, beethings also does some design work (including the beethings pattern below) under the name BarfootWorldwide. Check out their portfolio right here.
