Christina Clarke is a Liverpool University graduate, a committee member of the Liverpool Victorian Society and a founder member of the Save Our City Campaign. She will be talking to us about the history and contents of the Walker Art Gallery - which she describes as "a representation of the best of European Art of all periods".

This gallery, of course, was the gift of a Gateacre resident: the wealthy brewer Andrew Barclay Walker. It has benefited from generous bequests of paintings and funding, not only from Walker but also his son Lord Wavertree and other prominent individuals.

Christina will illustrate her talk with six slides of famous paintings which are on display in the Walker gallery. She describes one of these as "my favourite painting in the world". Can you guess which one it is?
