Mr Z told us that he entered the charity’s lottery that guarantees the entrant a one-off edition item. He said that the lottery stated that each item comes with a "signed" certificate of authenticity. Mr Z said that when the tickets were drawn he won one of the top prizes. However, he said that he was “really annoyed” to find that all the certificates had laser printed signatures. Mr Z said that this could reduce the value of the items and so felt that he was misled into entering the lottery.
