Vaughan played some fluent strokes on the first morning
Captain Michael Vaughan made a cautious start as England reached 91-2 at lunch on the first day of the second Test against the West Indies at Headingley.
Vaughan, who came to the crease after Andrew Strauss fell for 15, struck four fours to reach 25 on his Test return.
He shared 53 with Alastair Cook, before Cook fell lbw to Chris Gayle for 42 off the final ball of the session.
England recalled seamer Ryan Sidebottom after a six-year gap, while West Indies were without injured Shiv Chanderpaul.
Vaughan, returning to the Test arena after an 18-month absence because of a series of injuries, chose to bat as early cloud gave way to sunshine.
Strauss might have gone first ball when he fended a short ball from Daren Powell uppishly but Daren Ganga was deeper than the standard short-leg and could not gather diving forward.
Powell and new ball partner Corey Collymore were inconsistent again and Strauss latched on to two loose deliveries to despatch trademark square cuts.

A routine outside edge failed to carry to first slip, Gayle receiving a painful knock on the shin that was to require treatment in the pavilion.
But Strauss added only a single before his main strength proved his undoing in the ninth over as he attempted another cut at an even wider one from Powell and got a bottom edge to wicket-keeper Denesh Ramdin.
Vaughan took 34 balls to record his first boundary, swivelling to pull Powell through mid-wicket.
Contrasting, consecutive boundaries quickly followed off Taylor, a thick edge through the gully followed by a sumptous, classical off-drive as the captain began to find his touch.
Cook, who has yet to score a duck in Test cricket and has been dismissed in single figures only five times in 28 innings, comfortably moved towards his fifth half-century.
Gayle was given the almost customary pre-lunch over of spin, but far from being a token of uneventfulness, it brought the languid Jamaican reward.
Umpire Asad Rauf continued his policy of giving spinners lbw decisions that often used to be denied them when he gave Cook out propping forward defensively.

Vaughan had scored 72 in Yorkshire's first inningsEngland captain Michael Vaughan is likely to miss the first Test against West Indies on 17 May after suffering a broken finger during a county game.
He was playing for Yorkshire against Hampshire when he was hit by a rising ball from Australian Stuart Clark.
He has an undisplaced fracture to the middle finger of his right hand.
"It looks like he might be out for three to four weeks, but it's too early to say with absolute certainty," said Yorkshire physio Scott McAllister.

"It's desperately bad luck for Michael after the succession of problems he's had to contend with, and we will be monitoring his progress over the next few days," he told the Yorkshire Post newspaper.
However, the England and Wales Cricket Board have not yet ruled the 32-year-old out of the match.
"Vaughan will undergo further assessment ahead of the first Test match against the West Indies at Lord's on May 17," read a brief ECB statement.
Vaughan has not played a Test match since December 2005, having sat out the whole of last summer and the winter Ashes series following knee surgery.

He suffered a hamstring problem after making his comeback during the one-day series which followed the Tests in Australia, but recovered in time to play in all England's matches at the recent World Cup.
The match against Hampshire at the Rose Bowl was Vaughan's first since returning from the Caribbean and he looked in good form making 72 on the opening day.
He was 16 not out in the second innings when he was struck by Clark and forced to retire hurt. The fracture of his right middle finger was later confirmed by x-ray.
If Vaughan is ruled out of the first Test at Lord's, England will face a dilemma over who should replace him as skipper.
Andrew Flintoff led the team in the Ashes Tests, but was stripped of the vice-captaincy for disciplinary reasons during the World Cup and is unlikely to be elevated again.
It may therefore come down to a straight choice between Andrew Strauss, who stood in for Vaughan during last summer's series against Pakistan, or Paul Collingwood.
"To get mentioned with the captaincy is obviously a great feeling. But Michael's been doing a fantastic job. He may yet be fit for that first Test so we'll just going to have to wait and see," said Collingwood.
"I've done a few games for Durham a couple of seasons ago.
"I enjoy the challenges of captaincy but, as I've said, hopefully this will be in the future and hopefully Michael Vaughan will be fit."
