Plate 7
The "O" Flaw Stage 2 appears on most stamps from AA to GF.
"O" Flaw Stage 1 appears on the remainder of the G row,
H row, I row, and a couple of stamps of the J row. The
remainder of the stamps do not show the flaw. Early impressions
are intense black but later printings appear in gray black, although
there is no evidence of plate repair. This plate was
used for an experimental printing on thin light paper.
The Plate offers very little in the way of clues to aid in plating its
stamps
except for a narrow check letter E.
