Wobbe Vegter from South Africa has produced a wonderful website about Computer stamps. It includes the
topical exhibit From Abacus to Internet,
a 90-page display awarded Gold at Capex 2005 in Cape Town.
There are also several articles written by Wobbe about Cyber Philately.
A collection of stamps showing the history of computing from the earliest counting tools to the modern laptop.
This display by Johann Vandenhaute was shown at Amphilex 2002 in Amsterdam (Netherlands) and was
awarded 84% or Vermeil.
