Christy Mathewon children's glove Goldsmith JG8

Unfortunately, this glove is not my own, but a friend's. He found it 20 or so years ago in a goodwill store in Seattle. It's in great shape (better than my photography)
My knowledge of vintage gloves is in its infancy. While the condition of this glove no doubt makes it rare, is it a difficult model to find in any condition?
