At the turn of the millennium, a Japanese company issued a set called "Remembering the 20th Century," including toys of 20th-century icons--electronics, cartoon characters, vehicles, and so forth. Even the "Tower of the Sun," designed by artist Taro Okamoto for Expo '70 in Osaka, was included in the series.
2001 年的新世紀初，日本廠商推出「懷念 20 世紀」系列食玩，內容包括各種電器用品、卡通人物、交通工具等，甚至連藝術家岡本太郎設計、1970 年大阪萬國博覽會展出的「太陽之塔」，都網羅其中。
