Painting glass on the inside is a traditional craft that we use to produce these decorative balls that look great as christmas ornaments. Every year in the autumn we design 3 or 4 new images featuring either revolutionary propaganda or scenes of Shanghai so that they are hot off the press in time for the festive season. Each year we include a Mao Period Hero in our selection and, with these, we put a description of her or his exploits that earnt the official title of Hero inside the box just in case you've forgotten these legends.
