Plate impression, 21½ by 22 mm., in color, on white paper, slightly tinted with pink, perforated 12, grilled and not grilled. 30 cents, carmine and blue. _Error._ There is also an error of this stamp in which the flags are reversed. It is also stated to be an error on the plate, but may be only an error in printing. NINETY CENTS. Portrait of Lincoln in an oval, looking to the right, surrounded by ornamental scroll work, numerals "90" at each of the upper corners, set diagonally in outline, and shaded on vertically lined ground. On a label with rayed ground, edged by a colorless and colored line, in outline capitals shaded, "_U. S. Postage_" at top of oval. "_Ninety_" and "_Cents_" on scrolls at the lower left and right corners of oval respectively, set diagonally and in colored capitals. In outline Gothic capitals "_U._" and "_S._" at the lower left and right corners of the stamp respectively. Colors: portrait black, surrounding ornamental and scroll work, carmine. It may be well to add that the portrait is three quarters face, on a square hatched ground, and a single colored line in same color surrounds the oval at a little distance. The space left in the frame for the picture is bordered by fine short horizontal lines, which show when the picture is not properly placed. Plate impression, 21½ by 21½ mm. square, in two colors, on white paper, slightly surfaced pink, perforated 12, grilled and not grilled. 90 cents, black and carmine. The grille in this series is a square 9½ by 9½ mm. composed of 11½ rows of 12 smaller squares each, apparently separated by raised lines crossing each other at right angles, each little square divided by depressed diagonals also, as if produced by forcing a series of pyramids set close together, but not touching, into the face of the stamp. Seen from the reverse, the dividing lines are depressed and the squares stand up like pyramids, with ragged edges showing the broken fibre of the paper. The numbers of the several values of this issue is approximated as follows: 1 cent, 24,988,100 2 cents, 114,058,000 3 cents 530,346,800 6 cents, 6,363,700 10 cents, 5,770,130 12 cents, 4,088,875 15 cents, 2,360,740 24 cents, 414,325 30 cents 513,180 90 cents, 77,650 XXIII.
