In Night in Question, when LaCroix gives a bottle of human blood to an amnesiac Nick Knight, he dresses up the present with a gift tag. And, as the proprietor of the Raven, the tag that LaCroix uses is one that figures the logo of his night club.
Like most gift tags, the Raven tag has a small hole in the upper left corner. Through this, a narrow red ribbon has been threaded. LaCroix ties this ribbon around the neck of the bottle in a small bow.
