We are asking people to study the photographs very carefully and share them as far and wide as possible in the hope that somebody may recognise something.
Even though it is two years on, any of the items, if found, could still be forensically analysed and could provide a vital clue - the only clue so far - about what has happened to Leah.
If you recognise anything in our gallery, please call police on 101, quoting Operation Dawlish. Or, if you don't want to be traced, call Crimestoppers anonymously on 0800 555 111.
There is is £10,000 reward for information that leads to Leah being found.
