Okay...I have limited knowledge of philatelic and/or historical paper, apart from a bit of stamp collecting as a kid, so here goes.  Our uncle was a serious philatelist and we're just beginning to get a handle on his vast collection.  We're currently listing a batch of Federal Duck Stamp Plate Blocks for your collecting pleasure.  All were found in an old stock book and have likely been undisturbed for decades.  Please examine all large images for condition details.
