I have a redware pottery vase with a mark incised on the bottom. It is 6 1/2" high 6 1/2 wide. The mark is 3 pine type trees with a line under them. The middle tree is the largest. It is 1/2" high 3/8" wide. The bowl it's self looks like Rowantrees from Blue Hill ME.
I have looked everywhere for the mark but have been unable to find one like it. If anyone has any idea who made it I would appreciate the information.
