A chilly winter day might not be the best for an elderly reunion. But for two esteemed artists, Shao Bolin, 90, and Jin Shangyi, 86, such a meeting is of great value to relive the excitement of a collaboration that happened more than three decades ago. Jin joined Shao for a retrospective exhibition on the latter at the China National Post and Postage Stamp Museum in Beijing on Dec 20. Shao is a retired chief designer of China Post. The exhibition paid tribute to his career spanning decades, with dozens of iconic postage stamps he designed or co-designed with Jin and other artists on show.
