Interesting nautical decorations Mystery

This has me stumped. I do not know what these are for. They open up similar to an umbrella and the one has a beautiful sailor woman on it and the other one has a lighthouse. They stand approximately 14 inches tall when they are folded back together. A very very fine thread netting covers the bottom and the object sits on top. Does anybody know what these are? They look absolutely beautiful, but what could they possibly be for besides just decorations?
