VERY FINE AND RARE PAIR OF WORLD OF DINOSAURS SHEETS SHOWING BOTTOM AND TOP HALVES IMPERFORATE. ONLY TWO OF EACH ARE KNOWN.
The Datz book states that there is only one sheet of bottom half imperforate and two of top half imperforate. However, we offer another bottom half imperforate in the following lot, so either Datz has the quantities reversed or there are two of each. In either case, this pair of error sheets is one of the rarities of modern error collecting.
