Quentin Blake's famous illustrations of The Twits, Matilda and Fantastic Mr Fox all feature on a new series of stamps from the Royal Mail, issued to celebrate the work of Roald Dahl.

Out from tomorrow, the stamps also show James and the Giant Peach and The Witches, while a triumphant Charlie Bucket from Charlie and the Chocolate Factory is brandishing a golden ticket on the new first class stamp. Meanwhile, the 30th anniversary of Dahl's classic children's novel The BFG is marked this year with a sheet of four stamps showing scenes from the Big Friendly Giant, as well as an illustration depicting the meeting between the giant and the Queen, and a quote from the children's novel: "'Your Majester,' he said. 'I is your humbug servant.' He bowed again."

Dahl's daughter, Ophelia Dahl, said her father would have been "thrilled" about the stamps. "My dad wrote thousands of letters home throughout his life and never dreamed that one day one of his own characters would grace a stamp," she said. "This is an excellent way for us to kick off a year of celebrations to mark 30 years in print for The BFG and it's great that the stamps include a collector's set, devoted to The BFG and other characters from this book."

Dahl died in 1990. His writing for children and adults is published in almost 50 languages, and his books have sold over 50m copies in the UK alone.
