Pneumatic post is system to deliver letters through pressurized air tubes. These systems were used in several large cities since the second half of 19th century but was abandoned during 20th century.
Stations of pneumatic post usually connected post offices, stock exhanges, banks and ministries. In some cases, the postal administration issued special postage stamps intended for use on pneumatic mail.
The technology is still used on small scale - within hospitals or factories - to deliver small objects.
