Pull out the soft centers of each half of the bread. Generously brush the inside of each half with the melted butter and lightly toast the bread in an oven. Arrange the fried oysters on the bottom half of the bread, then set the top half over them.
Or, after toasting the bread, spread the tartar sauce on the bottom half of the loaf. Arrange the lettuce on top of the tartar sauce. Arrange the tomatoes on top of the lettuce. Layer the oysters over the tomatoes and set the top half of the bread over them.
Cut across into 2 to 4 pieces to serve.
