The artist is Rachel Cohen and she really does a lovely work on her diverse set of paper dolls.
This particular set has some nice research that went into it and I think they do a great job to illustrate period costuming! She even includes period shoes and accessories. This doll has both a color print out and a black and white one that little Vikings can color themselves.
I also recommend checking out some of her other historic paperdolls. The Saxon set is particularly lovely as is the Medieval and Cranach Gown! I can seen many a young SCAdian being enchanted with these. (Some of her fantasy dolls even remind me of my beloved sets of Star Princess paperdolls from the 80s!)
