U.S.A. Mostly ★★. The popular 'back of the book' ducks complete from Sc #L1 through to #L44, all mint never hinged! Also accompanied by plate blocks of 4 of ducks from the 80s. Minimum catalogue over $5500 as of 2015 Scott as hinged, would be a lot more today. To see such top quality in one collection is unusual, virtually every item would make a good sinlge lot in its own right. Perfection. The entire lot is presented at www.philea.se.
