Luk Mo-ping, 75, points to a school photo of himself when he attended Queen's College in Causeway Bay in 1950. The photo is part of a collection of school memorabilia on display to celebrate the college's 145th anniversary. The school was established as Central College in 1862 in Hollywood Road, and the exhibition - at the Hong Kong Central Library - includes exam papers, graduation certificates and old copies of the campus publication Yellow Dragon.
