Tiny Ship in a Bottle

Since finding a winder-in-a-bottle whimsy this past summer, I've started paying some attention to ships in bottles, too, though I don't really know enough to distinguish fine ones from cheap tourist souvenirs. This is the first one I've really fallen in love with--tiny (which I always prefer), upright, and super sweet, with two masts and three little paper sails on a blue boat amid  a green sea. I really love love this, and have a sense that the bottle is fairly old (it is marked with a B and a 6 on the bottom.) The pink seal at top makes for the perfect final touch.

2 3/8" tall x 1 5/8" wide x 5/8" deep. Great vintage condition.
