Hi, I have a great collection of rare duck decoys carved by Harry "Dead Eye" Ackerman of Lincoln Park, MI. Our family is also from Lincoln Park. I am showing a decoy with a carved back and also with painted wings. I also have a sleeper and 2 others that the wings are carved out. These are quite rare as the experienced collectors have not seen before. Harry has some decoys in a local and state museums. He was known for working decoys that would attract birds. Thanks for looking. Please contact me for info and prices.
