May 1, 1999, saw Leeds lift the famous trophy for the first time since 1978 following a record-breaking 52-16 win over London Broncos.
Incredibly, London went 10-0 ahead and were in front again soon after the break, before being swept away in a blue and amber tide.
Winger Leroy Rivett led the way with a four-try performance which earned him the Lance Todd Trophy as man of the match.
Here’s 21 superb pictures – of fans, players and coaching staff – from one of the greatest occasions in Rhinos’ history.
