1964 Paris Philatec Special Limited Issue Souvenir Sheet, based on Scott #580, these special edition souvenir sheets are not listed in Scott as they were not generally available from the Post Office; they were printed in small numbers and only distributed to ranking Officials and dignitaries. The sheet is mint never hinged, very fine and fresh. Yvert & Tellier lists this as "Bloc special 5" at 1,150 Euros. (Image)
