Couldn't see a name brand on the old papermache ones. It does say Victor decoy company on the plastic ones.
It's all in the timing to get the most money from your used decoys. I have sold hundreds of used decoys and had my best success around Thanksgiving time here in Oregon. Waterfowl season is in full swing here and birds are here in big numbers and lots of hunters have the fever, and are willing to pay top dollar. In comparison if you try to sell during the summer, or off season after the season ends, most people aren't interested.
