In the year 2014 these envelopes went out. The proces is a complicated one.

  1. First the envelopes are painted with coloured dots. Each colour needs to dry before the next one comes.
  2. The address and postage stamps are added
  3. Some special rubberstamps are added
  4. The letters are added to the side, and because they are two sided the backside is also marked with these words
