Northwest Coast carving?

This looks like a small reproduction grease bowl, used to put Eulachon oil (smelt) or other condiment for dipping.
Seems Philip Thorn was an artist and found a way to make resin casts to make his art more affordable. Does anyone know more about him? His name is on a lot of masks, totems and other items. Do his items hold value as vintage art for the tourist trade?

 

As mentioned in the other thread on Thorn Arts: Thorn arts was a casting firm, and was not engaged in making reproductions of wood carvings, but in making souvenir-quality cast items.
I've never seen a wood item with a Thorn signature. Though dating to the 1970s, their value is minimal, and they are not highly collected. Value for any Thorn item should be in the $50 range at most, unless misrepresented as an old or genuine wood carving.
