Ethan Allen Thumb Back Chair

This is a single wooden chair made by Ethan Allen, it has "Thumb Back Chair" painted across the back of the seat and on the bottom it has a stamp that says "Ethan Allen American (word I can't make out) Solid Maple and Birch". That is all of the information I have about this chair, I have done extinsive searches on Google and Ebay and I have not been able to find any chairs that are just like this one. I was wondering if anyone had any information about this chair and how much it is worth, I am interested in selling it.

Thanks a bunch
