Hi, DeForest is Margaret DeForest who made these potteries in Duarte,Calif. along with her husband out of their house or garage. I beleive she designed them also. My cookie book has many pictures of these cookie jars but they all don’t have a number associated with the jar. If you could discribe your jar I might be able to help you more. There is 3 jars that are valued at more than $1000.00. Others range from $95.00 to $600.00. So either way you made a very good buy. There business was 1950-1970
