Wikipedia says;
A short snorter is a banknote inscribed by people traveling together on an aircraft. The tradition was started by Alaskan bush flyers in the 1920s and spread through the military and commercial aviation.[1][2] During World War II short snorters were signed by flight crews and conveyed good luck to soldiers crossing the Atlantic.[3] Friends would take the local currency and sign each other's bills creating a "keepsake of your buddy's signatures".
