Abstract

Printed in multicolour using five different colours for each value in issue X, six in issue Y and five in issue z. Colour checks in the form of coloured discs 3mm in diameter, are seen in the right hand margin next to the last stamp of the bottom row, in issues X and Z, but next to the last stamps of the two bottom rows of issue Y. This was so in all Panes, of all values, of the three issues. Colours from top to bottom correspond to the colours used for Pane numbers from left to right, on all Panes, of all values, in issue X, but from right to left in issues Y and Z, except in the 7c value of issue Z, in which they are from left to right. Cumulative totals of progressive columns are seen in top and bottom margins, printed in black, in all Panes of the three issues X, Y and Z. [excerpt]
