Although the idea of a banknote with graffiti all over it makes me cringe, some are interesting in the content of the writing (providing the note isn't rare!). Short snorters fit that category and are an interesting phenomenon, with a significant historical tale.
A short snorter is a banknote which was signed by various persons traveling together or meeting up at different events and records who was met. The tradition was started by bush pilots in Alaska in the 1920's and subsequently spread through the growth of military and commercial aviation. If you signed a short snorter and that person could not produce it upon request, they owed you a dollar or a drink (a “short snort”, aviation and alcohol do not mix!).

This is the Ledo Road Short snorter, commemorating the Ledo Road construction project during World War two.
It is signed by a lot of senior people of the time, including Louis Mountbatten.
The Ledo Road, from Ledo, Arunachal Pradesh, India to Kunming, Yunnan, China, was built during World War II so that the Western Allies could supply the Chinese as an alternative to the Burma Road which had been cut by the Japanese in 1942.
