Seances give doorprizes?

Odd sales item. The auction title says it is A Visit with Lizzie Borden Evidence Bag. And it is rare. I’m intrigued. What could this mean? Oh, it says that it was a giveaway at a seance at the Lizzie Borden B&B. They give prizes at seances? What for? The most blood-curdling scream? The first one who sees the ghost of Abby? The person who can correctly guess who is making the most money off of this seance? At $15 and $5 shipping, I think the person selling this bag is the one who is trying to make the killing.
