1c Blue, Ty. Ia (6). Rich Plate 4 color on bright paper, large margins to touched, unobtrusive cancel at bottom right leaves entire design clearly visible

FINE AND ATTRACTIVE USED EXAMPLE OF THE 1851 ONE-CENT TYPE Ia IMPERFORATE, SCOTT 6.

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 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).
