Pos Malaysia released a set of bird definitives on May 14, 2005 to replace the long running fruit definitives (issued in 1986). The definitive set contained eight denominations - 20s, 30s, 40s, 50s, 75s, RM1, RM2 and RM5. These definitive stamps were printed in the format of sheet-of-20 with inverted watermark. The Pos Malaysia logo was printed at the bottom margin of the sheet. It is understood that the format of sheet-of-20 was specially issued for collectors, and for the normal use in mail, the stamps would be printed later in format of sheet-of-100.
Up to May 2009, only five denominations of the bird definitives have been printed in sheet-of-100 (I call it as new print). The Pos Malaysia logo is printed at the top margin of the sheet. The denominations are 20s, 30s, 50s, RM1 and RM5. These new prints have upright watermark.
