Old Tom's Tale

A series of stained glass windows in Leadenhall Market at the moment. They tell the story of Old Tom, a goose born in 1797, that escaped slaughter, was adopted as a mascot of the market, and went on to live for nearly 40 years.
There is apparantly a trail of these windows, but I have only seen two, so I'll have to go back and seek out the rest. They are there until 14th November.
