The Knights of Arthur

Sailors Sam Dunlap and Arthur check in to a New York hotel to await their mate Vern Engdahl when a girl shows up proposing to purchase Arthur. They need guys like Arthur to help run the city, and the fact that he fits in a small suitcase is even better. - The Knights of Arthur was first published in the January 1958 edition of Galaxy Science Fiction magazine.
