The Postal Museum has a unique collection of artefacts. No other museum has similar objects related to postal services. The collection includes objects like postal signs, vehicles, sealing equipment, postboxes, uniforms and workwear. There are also many more common objects used at post offices, such as furniture and general office articles. The total size of the collection is more than 9,500 items, including Posti’s first vehicle from 1911 and the world’s first eLetter computer from 1986.
Most of the collection has come from post offices, but private individuals have also made donations, uniforms in particular. The oldest artefacts date back to the 17th century, but most are from the 20th century.
