folk art carved duck decoys

Hello, does anyone know of who may have carved these wood decoys, from the weights I would guess early 1900,s . I find the painting quite unique . At first I thought it was sanded but I think it was purposely added this way . Also since I found two examples. Anyway any thoughts appreciated , They are about 12-14" and Red Cedar wood. Found in central Minnesota so perhaps a carver here. Thanks
