Its work in the intervening period has seen it fund the building and development of Noonkodin Secondary School in a remote area of the Maasai savannah in Tanzania.
The charity also seeks out sponsorship for individual pupils at Noonkodin — who today number 200.
Titled Africa Proud, the exhibition at the Old Fire Station Gallery in Henley’s Upper Market Place will showcase the work of photographer Bob Webzell.
He will be donating the proceeds from any photographs that are sold to Serian UK, of which he is also a co-founder.
Mrs FitzGerald, who was mayor from 1992 to 1993, later went on to study anthropology at Oxford Brookes. It was during a visit to Tanzania that she and a fellow anthropology student decided to found Serian UK.
She said: “Our core funding is our sponsors that sponsor students through secondary education.
“In a country like Tanzania there is no free schooling. Those that are very poor — and there are many, many people who just don’t have any extra money because they’re living at subsistence level — have no chance of getting a secondary education or moving on further.
“So, therefore, anybody who is sponsored is really lucky because they get the sponsorship fee, which helps their families, which helps them, and in turn they then want to educate their children.”
Africa Proud runs until Monday. Opening hours are 11am to 4pm daily.
