Atom use & Models

To be extremely brief in describing this very complex subject, in 1805 Englishman John Dalton – considered to be the originator of modern atomic theory – proposed that each element that exists consists of atoms of a single, unique type, and that these atoms can join together to form chemical compounds. Although academics from earlier centuries and different cultures had also theorized about the existence of atoms, far greater understanding of the subject came about in the early part of the 20th Century when German (later to become American citizen) Albert Einstein produced papers and equations which eventually led to other important scientific developments towards our knowledge of atomic and molecular theory. His work also pre-empted the use of nuclear energy to produce the atomic weapons first used in the Second World War, though he was a pacifist. Many stamps have been produced to celebrate the various discoveries and achievements by atomic scientists over the years.

Insects have a three-part body consisting of the head, the thorax, and the abdomen. They have three pairs of jointed legs, compound eyes and two antennae. The number of extant species is estimated at between six and ten million. The life-cycles of insects vary but most hatch from eggs. Insects typically move by walking, flying or occasionally swimming. Humans regard certain insects as pests. Other insects are considered economically or ecologically beneficial, like silkworms and bees. The ancient Chinese regarded cicadas as symbols of rebirth or immortality.

Ducks are mainly aquatic birds. They feed on a variety of food sources such as grasses, aquatic plants, fish and insects. Ducks are generally monogamous. Most species breed once a year, choosing to do so in favourable conditions mostly in spring or summer. Worldwide, ducks have many predators, with ducklings being particularly vulnerable since their inability to fly makes them easy prey for predatory birds, some species of large fish and also crocodiles.

Ducks have many economic uses, being farmed for their meat and eggs. They are also kept and bred by aviculturists and often displayed in zoos. The word "duck" may have become an inherently funny word in many languages, possibly because ducks are often seen as silly in their looks or behaviour. Also possibly because of the association with the cartoon character Donald Duck from the Walt Disney film.

Alt_Text Welcome to our shop in Haarlem. Our hostess will welcome you with a cup of coffee. The opening hours are Wednesday to Saturday 10 -17h.

Haarlem is our headquarters. It is where owner Rob Smit began selling stamps in 1983. Over the years PostBeeld has expanded to include two adjacent buildings and now this is, with over 200m2, our largest store. Our headoffice is also situated in Haarlem. Here our websites are maintained and part orders from other locations merged into one and sent to our customers. The shop is located at 17 Kloosterstraat. A large public car park (Cronje) is a short walk from the store. Haarlem railway station can be reached on foot in 10 minutes. Our headoffice is located at Emrikweg 26B.

Alt_Text Welcome to our shop in Leiden, where Jaap is your host. The shop is open from Wednesday to Saturday (inclusive), from 10.00 to 17.00 (other days by appointment only).

De Leidse Postzegelhandel is one of the oldest stamp shops in The Netherlands, in business since 1941,and situated in Vrouwensteeg 3 in the heart of the old centre of Leiden. In October 2014 ownership transferred to PostBeeld, thus becoming the third PostBeeld store. The shop will continue to operate under the old name we respect so much with the addition of PostBeeld in the title to become “PostBeeld, de Leidse Postzegelhandel”. Vrouwensteeg is a street off the Haarlemmerstraat.

In this shop you can find albums, storage systems, catalogues etc. Both new and second hand. There is always a good stock of stamp books, with prices from a few euros to those worth hundreds. These books can be viewed only in our store. Unlike the rest of PostBeeld’s stock, they are not available to view via the internet. The shop also has a fine stock of coins and banknotes.


Behind the scenes we work with great care to process your order. At our Haarlem headquarters there is a lot of activity. About 25 people work here on two locations dealing with customer orders and administration.

Although our stock is held at around ten different locations in Europe, the Haarlem shop holds the greatest part of PostBeeld's stock and the purchasing department is also based here. If parts of an order are located elsewhere, everything is gathered together in our Haarlem office before being despatched to the customer.

Our translators and customer service department staff are also based in Haarlem. In the photograph above orders are picked from our stock. Below are some behind-the-scenes PostBeeld photos.
