XXV Olympiad 1992 issue - X, historical buildings - Y

Abstract

Issue X was printed in multicolours using the same four colours for each value. Issue Y was printed in solid colours using three different colours for each value, with two of them being common for each value. 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 all Panes, of all values, in issues X and Y. The colours from top to bottom correspond to the colours used for Pane numbers, from left to right, in all Panes, of all values, in issues X and Y. Cumulative totals of progressive columns of stamps are seen in top and bottom margins, printed in black, in all Panes, of all values, in issues X and Y. [excerpt]
