Thank you... who ever you are...
The Pneumatic Tube System was invented in the 1850's. Being born in the late 1960's, it is a big gap in time. Time I could not make my own photographs of pneumatic tube events... So I can only use photos and drawings made by other enthusiasts.
Many, many thanks to all those who made it possible for me to show that information to you now!
When making this website I used Public Domain and Creative Commons images.
Also Open Source and MIT scripts and code from several other websites.
Hereby I want to give them credit and gratitude!
