There are souvenir stamps on postcards from colonial Taiwan marked "S.S. Franconia" at the website: Michael Lewis Taiwan Image Collection (this site will not allow URLs to be posted).
To view these cards, just type "Franconia" into the search box. There are also a few other cruise-ship cards, from the "Resolute" and the "Laconia" for those who are interested in where these ships docked and the types of souvenirs the passengers obtained.
