CROWDS of Penarthians queued up to see Welsh rugby star Sam Warburton at a book signing in the town centre on the weekend.

British and Irish Lion Sam posed for photographs and signed autographs during a two hour stint at Windsor Bookshop on Saturday.

The bookshop estimated that they would sell out their stock of more than 300 books as people rushed to get a signed copy of Sam’s book ahead of Christmas. Tony Hallett, who owns Windsor Bookshop with his wife Anne, said it was the busiest they had ever been and that Sam was probably the most famous person they’d ever had there.

Wales captain Sam, who had been in Swansea earlier in the afternoon for another book signing, was signing copies of his second book, Lions Triumphant - The Captain's Story.

"I've written two books and I'm only 25 so I don't think I'll write another one until I retire," he said.

"I'll leave it until then to write a controversial one!"

He added that he still found it "surreal" that so many people came to the book signing to see him.

"I'm like a lot of the Welsh rugby lads and am pretty down to earth," he said.

"I'd like to thank everyone for coming."

Youngster Aston Baker had his Welsh rugby shirt and book signed by Sam.

"It was really good meeting him and I'm looking forward to reading the book," he said.

Aspiring fly half Aston, who plays for Dinas Powys RFC, added that Sam was his favourite player.
