The members of the POSTAUMAAT Stamp Club collect stamps, booklets, automat stamps and postage labels from The Netherlands and the rest of the world.Every three months members receive the BULLETIN with articles and pictures of new issues or peculiarities. Presently the BULLETIN appears only in Dutch. In March, June, September and December meetings are held, in which club members can trade, sell or buy stamps and booklets. An auction with attractive lots is held during every meeting. Members who are unable to attend the meetings, can put their bids in advance by letter or email. POSTAUMAAT also offers a circulation system of items for sale at preset prices.
