It is one of the most abiding sights in a Challenge Cup final: the grinning face of Henderson Gill after his try in the 1985 thriller against Hull.
That final is widely regarded as the best in the competition's history.
The see-saw battle had it all: great drama, great tries and that great, big grin of Gill's.
Wigan eventually won 28-24 in front of 97,801 fans at Wembley - but Hull played their part in one of rugby league's most thrilling contests.
Here, BBC Sport's Dave Woods recalls his memories of that famous final:
The Australians Brett Kenny and John Ferguson were the stars for Wigan, Kenny revealing his coolness before the kick off by sauntering onto the famous Wembley turf with his hands sunk deep inside his tracksuit top.
He went onto scoop the Lance Todd Trophy as man of the match, scoring a sublime individual try.
Not sensible play this by Wigan, normally a side would take the ball away from the posts to avoid any goal kicks. Oh, good ball from Kenny, to Stephenson, he's got Gill outside him! Now then, he's got 60 yards to go, can he go round Gary Kemble? Oh, he's beaten him. Oh, as good a try as you'll see. All made, for Henderson Gill, by that beautiful pass from Brett Kenny!
Ray French commentates on Henderson Gill's wonder try
Ferguson, the enigmatic winger from Eastern Suburbs, struck once in each half, his second try coming only moments after commentator Alex Murphy had famously insisted he was carrying a leg injury and should be stretchered off.
Henderson Gill also went the length of the field, revealing a toothy grin as wide as the Royal Box after touching down, while a teenage Shaun Edwards completed the Wigan scoring.
But Hull, 28-12 down with 16 minutes left, produced a stirring fightback, which was inspired by Aussie scrum-half Peter Sterling.
James Leuluai, twice, and Gary Divorty sprinted in for thrilling touchdowns to make for an almost unbearable finish.
But the Airlie Birds were left kicking themselves - literally.
Lee Crooks landed two penalties, but he and Garry Schofield were wide with each of five conversion attempts,
And that allowed Wigan to hold on for their first Challenge Cup success in 20 years.
