Commemorations 1990

4 stamp records · 3c / 4c / 19c / 20c

Ordinary basic design/value types plus explicitly documented major watermark differences. Excludes postage dues (separately researched), unchanged reprints, repeated formats, plate/pane numbers, errors and minor varieties.

Research notes: The perforation table repeats 20c in its second row although other fields identify 19c. The unresolved 19c measurement is omitted. Value-specific subjects remain unmapped.
