Duck Permit Collection. Complete to 2006, all but the last 13 are displayed in 4 frames with printed matts published by American Wildlife Art Gallery; the spaces are recessed and the stamps themselves are in hingeless mounts; it is impossible to determine the hinging without disassembling the frames but the stamps are definitely not pasted down; most attractive and high catalog value and face value from the 1980's on. Scott No. RW1-RW73  Estimate $750 - 1,000. $0
