I purchased this nice little Sealyham Terrier from an antique dealer along with seven others all different breeds. The dealer purchased them out of an estate and said the gentleman made them all himself. I have not ever seen them before so it could possibly be one of a kind but I'm not sure. It measures 2 3/4"L x 2"T and I was told it is a composition celluloid. It looks and feels amazingly like wood to me with very nice detail and definitely is not hollow but solid and lightweight. It is nicely detailed and has a stained gloss finish. Condition is very good with no chips or cracks just the top of the head is lighter for some reason.
