This should help you !! Your figure is very correct in that the Mud Men figures should only have the glaze on the clothing, not on the skin and should have holes for eyes ears ect !! Read the article in the link above !! It tells what to look for in the older figures !!
Thank you marthahill I read the article, and do not see a CHINA stamp inside at all just the stamp in the picture. He has holes for eyes and ears, not mouth. So hard to tell but he is very nice any way. Spent hours looking, never found one similar, especially with such dark mud Carolyn
