The BBC's Antiques Roadshow never ceases to entertain and turn up items of extreme interest . Last night the show produced the above collection of hats which had belonged to the romantic novel writer Barbara Cartland, bought by a woman's husband at auction in 2000 for slightly more than 2000 pounds . Another unusual item was an album of paintings in the 1810-1840s period , valued at 10,000 pounds , of a Quaker household in which the gardener, Lockwood, wearing a top hat , was raking leaves . Strange indeed was the caul, the membrane which covered the head of a baby when he was born . It was supposed to be buried with him later in life , but he and his wife died within a short time of each other and were buried in a mass grave .
