Here is what looks to me to be a Mason Premiers Mallard Drake Decoy.
I am not an expert and do not have much knowledge about antique decoys but what I have researched tells me that the scrolled face separating the bill from the face, the way in which this decoy is painted, the glass eye and what appears to be a hollowed out body indicate to me that might be a Mason. If anyone has any information otherwise please advise. I will be listing two nearly identical decoys.
17 in long and 7 in tall to the top of the head and around 5 1/2 in wide.
This one weighs 2 lb
