Vitreous enamel washbasins were made as prizes for the winners of the Socialist Labor Competition. The center of the basin is stenciled with the character 'Prize' (奖 jiang); the interior wall is inscribed 'Socialist Labor Competition' (Shehui zhuyi laodong jingsai 社会主义劳动竞赛). 'Competition' 赛 is written in a simplified form that is no longer in use. The factory seal (not shown) reads 'Lanzhou Enamel Factory' (Lanzhou tangci chang 兰州搪瓷厂).
