'The Sirius' 
Bill Korsgard Collection
Written on the back of the card....

"No need of telling you what boat this is. I don’t know what’s the matter with her this year. She can’t do a thing. I think it’s because Ed., working at the shoe factory now, can’t get out and give her his attention. Quimby ran it in the races. Parker pulled a corker off on Quimby at the minstrel. He told Harmon, who was interlockter (?) that an awful accident happened at the race that afternoon. Harmon asked him about it and he said they had to get out a searching party. Harmon asked him what for and he said to go out and find Jimmy Quimby."

Finn mentioned this boat in another card when he compared 'Mercury of Oshkosh to her ..... "'Mercury' Oshkosh-She's a lot like the Sirius. The guy that killed a man with the Sirius owns her."
 There was an notorious  "pirate"  ice yacht  on Lake Winnebago named 'Cyrus' in some accounts. 'Cyrus'  was known for making moonlight excursions into small towns, stirring up the citizenry and wreaking havoc where ever it went. Could this be that pirate ship?
