The Esmé Squalor Fan Club was a club mentioned in Lemony Snicket: The Unauthorized Autobiography. They were mentioned to have bought the dead body of the Mamba du Mal at an In Auction. They are associates of Count Olaf and Esmé Squalor. In reality, they're a group of Fire-Starting V.F.D. agents.
In the TV series, Vice Principal Nero is the vice president.
It is stated that during the In Auction, the Esmé Squaor Fan Club won the deceased, framed Mambu du Mal that was originally owned by Monty Montgomery. Lemony Snicket notes that they are associates of Count Olaf, and there are fourteen in total- possibly excluding whoever took the picture.
