1c Blue, Ty. Ia (6). Plate 4, full margins showing much of the key design characteristics, just touching the plumes at bottom, deep Plate 4 color, circular datestamp cancel, a few minor flaws including small edge thin, tiny tear and corner creases

VERY FINE APPEARING EXAMPLE OF THE 1851 ONE-CENT IMPERFORATE TYPE Ia.

Stamps printed from Plate 4 were issued in April, May and briefly in June 1857 before perforations were introduced. The relatively small number of imperforate Plate 4 stamps issued during this period explains the rarity and desirability of any of the imperforate stamp types produced from this plate (Ia, Ic, II, III and IIIa). The extremely rare Type Ia, showing the full design at bottom, was furnished only by 18 of the 200 subjects on Plate 4 (the remaining two bottom-row positions were sub-type Ic).
