1998, History`s Greatest Fighting Ships”, unmounted souvenir sheet depicting on 25 stamps famous battle ships from a Roman Galley to the huge US Aircraft carriers of modern times. Due to a mistake in the printers` plant the sheet shows a stunning misperforation in that way that the bottom row of 5 stamps is horizontally cut in halves and producing sort of ”interpanneau” at the top. A lovely thematic (”ships”, ”maritime topics”) item! (M)
