AGE: Made between 1920 and 1930 (based on company history)

MOTIF: Not sure - is it Mephistopheles, Druid, Demon, Devil, Mask, Old Man in a Hood.
WHAT IS IT? I believe it was a promotional item given to prospective clients to show the remarkable process. It is quite an interesting object, the finish is similar to a kitchen sink or bathtub - very unusual and very cool. Most people would be familiar with an enamel cooking pan or dutch oven. It is that kind of material. A paperweight perhaps? I have shown it also hanging on the wall in one of my pics.
