HANDCRAFT

THE HONGKONG TELEGRAPH,

Wood Carving

ancient and modern

It has been the delight of crafts- men of all ages to transform plain solid material into a wonder of design and embellishment. A trans- formation which could only be achieved by hand.

It is the same spirit of handcraft allied with pure golden Virginia leaf which produces the World's most famous cigarettes.
