These were left to me by a recently deceased friend. I don't play bridge or know anything about it, so all I can do is described what you see in the photo: The blue "Bridge" book is one in a series of about 20 books. The "EZ Guide Companions" are a set of four. There are around 20 decks of cards. And those white sheets, which I guess are about setting up duplicate tournaments.
If you want any of this, you have to take the whole set; I'm not giving them away piecemeal.
