World's largest toy collection goes on sale

It has taken 50 years and millions of dollars to amass but now what has been billed as the world's largest toy collection has gone on sale in New York.

The collection of 35,000 vintage toys and trains is the result of a lifetime's dedication by one American collector, Jerry Greene.

He built up the collection over the years and kept them in five basement rooms of his suburban Philadelphia home.

They are now expected to fetch tens of millions of dollars.
