The black duck is a L.L. Bean Coastal Black Duck made sometime in the sixties -early 70's era in what looks like nice original paint. Nice find. The other bird is also very nice, maker Unknown, but a very desirerable nonetheless. Take good care of them. If you are going to hunt over them I would treat them like gold, as they hold some value. Baby them, especially the blacks because the necks will split because they use an iron nail as a pin to adjust the head to look left, right or straight ahead and the salt water rusts it and splits the neck after time. The tails are also fragile as they are a plywood laminate and fall apart unless you are very careful with them. If I were you I would put em on the mantle and use the nice plastic decoys that are on the market today.
I enlarged your picture and it appears as if the blackies head is fixed to the body. Hard to tell as the anchor line breaks it up, but it may be a George Soule original, and not the mass produced birds he made for Bean. If that is the case the value goes up. He could be worth $100 or so... too bad cork doesn't hold the value like wooden decoys, otherwise you might have been adding zeroes to that value.
