The celebrations for Paddington Bear's 50th anniversary are underway - with BBC Radio 4 today launching a promotion across train stations in the UK.
The channel has placed 50 Paddington bears in prominent places at key train stations from 9.30am this morning, all wearing the label 'Please Look After This Bear'.
In exchange for taking the bears home, the finders will be asked to call BBC Radio 4 and leave a special birthday message about the well loved bear.
On Saturday March 1st, in a special one-off programme, children's author Michael Morpurgo will talk to the finders, hearing how and where they found the bears, their favourite Paddington memories and what Paddington means to them.
Interwoven with these stories will be extracts from creator Michael Bond about how he came to write A Bear Called Paddington in 1958 and why he thinks the character has stood the test of time.
Top Gear presenter Jeremy Clarkson will also be speaking on the programme.
