Foro de Filatelia Argentina

A fine set of definitives was engraved and printed in the UK by Bradbury Wilkinson, New Malden. A few values had to be re-issued in different colours - due to a postal rate change? - in 1903. One might expect BW to use the same printing plates again OR having new plates made from the same original engraved dies. However, when you really pay good attention, you will see that BW had made NEW engravings for some values. Not for all [10c?] as a minute detail keeps popping up in the new colour as well!
