It is the boot of Paul Bunyan, who the fair folk must blame for urbanization. He was a lumberjack, after all, and a man of adventure. There just so happens to be some impressive Paul Bunyan statues in MN....
So after crossing the London Bridge you get to a boot shaped island. Looking at the Beachcomber BLVD you notice that it forms the shape of a woman with head, arms, body, smallest leg and foot. Her foot is practically standing on the marina. Now a couple of observations in the painting: • She’s wearing a slip and it is touching the water on the platform. • Her unusual foot and toes is in the shape of a duck’s head and bill, also touching water. • I take these clues as dock/slip in the marina. 7th slip is a good guess. Spot of interest is in the sand infront of 7th slip. • The painting may show the spot in the sand next to where dog lays with an iron probe in the corner
I know the battle axe and the Valkyrie line is sending people to Minnesota but it doesn’t fit the imagery.
Axe is connection to Native Americans and the line ‘Valkyrie's window with seven’ may only be a simple word puzzle.
