To help the modern children realize the mystery of the traditional toys of childhood, this Directorate released a second set of Children's Plays Postage Stamps. It features four native-style delights-grassfighting, iron-ring rolling, the chopstick gun and walking on ironpot. In addition, a souvenir sheet (150×100 mm.) composed of one each of the four stamps as well as a booklet consisting of two sets of the stamps were issued on the same day. The booklet stamps have two sides perforated, but the top and bottom sides are imperforate, the size of stamp is 30×40 mm.
