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.
