The stamp has multiple appeal among collectors of Netherlands and Colonies, Indonesia, and First Flight Cover collectors.
With about 16.6 million people, the Netherlands is the 16th largest economy in the world, and its annual GDP growth has averaged about 2.5% over the last 5 years. Indonesia is a rapidly developing, though still poor, country of 230 million people, with an annual GDP growth rate hovering around 5%-6%. Like most emerging market nations, it faces challenges which will have to be addressed, including corruption and major inequities in the distribution of income.
Those interested in becoming part of an international community of stamp collectors, dealers, and investors are encouraged to join the "Stampselectors" group at Facebook. The group hosts lively discussions concerning stamp investment and practical aspects of collecting, and provides a useful venue for those who wish to buy, sell, or trade stamps.
