Our earliest colour picture features Harry Gregg in green against Partizan Belgrade in Serbia back in 1966.
Here's Harry Gregg again, this time with David Gaskell, in the 1963 team photo.
Alex Stepney waves to the crowd before United earn a famous 3-3 draw v Real Madrid in the European Cup semi-final in 1968.
Green was the colour once again as the Reds lifted the European Cup at Wembley in 1968.
Alex Stepney, still in goal for United in the 1976 FA Cup final against Southampton, watches a shot go over the bar.
Stepney's safe hands were a feature of United sides for 12 seasons between 1966 and 1978.
Then came Gary Bailey, pictured here at Wembley in the 1979 FA Cup final.
Paddy Roche was the unlucky man who played understudy to Alex Stepney and then Gary Bailey.
There were better memories for Bailey at Wembley in 1983, as United beat Brighton in the FA Cup final replay.
There was more Wembley joy for Bailey in 1985 when the Reds beat Everton in the FA Cup final.
Here's Gary Bailey in the first goalkeeper shirt to feature a sponsor, back in 1982/83.
Gary Walsh is in a small group of keepers to rise from the youth ranks to regular first-team football.
Chris Turner was the first goalkeeper to play under Sir Alex Ferguson. Here he is in 1987.
The manager signed Jim Leighton from Aberdeen two years after his arrival at OT from the same club.
Leighton's joy in the 1990 FA Cup final was shortlived...
..as he was dropped in favour of Les Sealey for the replay, won 1-0 by the Reds.
Sealey was a regular in 1990/91 and helped United win the Cup Winners' Cup final against Barcelona.
Peter Schmeichel, perhaps the greatest ever United goalkeeper, signed that same summer.
Schmeichel was first-choice for eight years and finished his career in green, in the 1999 Champions League final.
The Champions League win was his 15th trophy in a United career that spanned 398 appearances.
Raimond van der Gouw was on the bench that night, a role he never complained about during his six seasons at United.
When Schmeichel left, Sir Alex signed Mark Bosnich, who'd previously been at OT as a youngster.
Green returned when Edwin van der Sar arrived in 2005. Barthez, Carroll and Howard never wore the colour.
Tomasz Kuszczak saved a penalty against Arsenal on his Reds debut.
Here's an unusual sight: Rio Ferdinand pulled on the green shirt at White Hart Lane after Edwin got injured.
But after some consultation, John O'Shea took over duties and kept a clean sheet.
Kuszczak was in green when United won the league at Wigan in 2007/08.
Van der Sar's finest moment, saving the penalty that won United the Champions League in 2008, came in green.
Edwin received plenty of praise for his heroics in Moscow. Here he is, lifting the cup.
Ben Foster made his United debut in green, away at Derby County.
The traditional green colour, as worn here by Anders Lindegaard, is back in 2011/12, after a three-season absence.
David De Gea wore green in his first United game, against Chicago Fire on the 2011 US Tour.
Ben Amos, the latest in a long line of promising young United goalkeepers, concludes our gallery.
