There wasn't any information on the sculpture, but a quick search of the Web revealed that it was made by Graham Ibbeson. His website is well worth a visit, and I really like his mixture of comic and quite poignant sculptures. There are times to be serious and there are times to just have a laugh, and I think Graham's sculptures cover both these situations well.
One I didn't know of, but will look for next time I'm there, is The Fair Maid of Perth.
I really like sculptures that aren't on a plinth, but are at street level so you can interact with them. How many visitors get their photo taken sitting next to her?
Graham has also sculpted figures from comedy including Laurel and Hardy, Benny Hill, Les Dawson, and most famously, Eric Morecambe
You've got to admit, this is much better than some sculpture of some long forgotten Victorian politician or industrialist that usually populates our town centres. So much better that it was unveiled by The Queen.
It's really strange how me seeing an unusual sculpture in passing has led me to a whole array of works that I'm going to try and go and see, but that's the power of the Web.
