According to Official Guinness Records,
Steven Smith (UK) has 1,054,221 different matchbox labels from over 130 countries as of May 2011.
Mr Smith has to have fire extinguishers in every room as a lot of the complete matchboxes still have matches inside. His interest in matchboxes started as a six-year-old when he and his friend used to go to Great Yarmouth seafront and collected empty matchboxes from the bin. These days Mr Smith has handed over his business and spends up to 10 hours a day on his hobby.
