Glass works

(Photograph) - Rare antique glass from America, Poland and Sunderland is pieced together in a stained glass window depicting some of Yorkshire's most celebrated structures including the Ribblehead Viaduct and the Humber Bridge. John Uren from Leeds University's school of civil engineering stands before the window, which was commissioned from Hannah Stained Glass to mark the school's 50th anniversary.
