I've no idea who he is, but I understand he's meant to be a hobbit, although I don't know how - big ears maybe?
With regard to the brushes, I tried the detail brush so the comments regard to that. I found it really very good, the quality of the hairs were really very good and the shape and size of them were excellent. I normally use a No.7 and to be honest can be quite brutal with them - they don't often last more than 2 or 3 minis before the point disappears. The Wamp one lasted effectively 2 minis before the tip disappeared. I understand they're very similar to a different UK well know and loved brush (that I don't use).
