Plate 4 imperforate stamps are rare and desirable because they were issued in April, May and briefly in June 1857, just before perforations were introduced. The extremely rare Type Ia, showing full design at bottom, was produced from only 18 of the 20 subjects in the bottom row of both panes of Plate 4. The position 97L4 "Curl on Shoulder" variety resulted from a tiny thread adhering to the relief during the transfer process.
