4 Vintage Placemats

Set of 4 identical placemats. I think these could go back to at least the 70's and maybe the 60's. I don't ever remember using these. But my parents honeymooned in coastal BC and south Alaska in the mid 60's. They feature Tlingit art of the Blackfish (also known as Orcas). There is a possible signature, but I couldn't find any answers on the Internet. There is a bit of a mark on one, I assume it would wash out. I'm pretty sure that they are made from natural fibers, maybe some type of burlap. That was a common placemat material back then. The back of one of the others has some paper or something like that stuck on. It's loose around the edges and maybe it will just come off. Maybe that was the packaging.
