补充资料:《封龙山碑》轴(初拓本)(Fenglongshan Bei Zhou
      清代重新访得后的汉《封龙山颂》原石初拓本。整纸装,纵 159厘米,横91.6厘米。碑文书法结字取势富于变化,行笔遒劲豪放,隶书那种"蚕头燕尾"的波挑笔式,不甚显著,横笔多出尖锋,垂笔近似"悬针",虽为隶书结体,又与一般隶书不同,有浓厚的篆书笔意和金石趣味。
  
  此本为最早拓本之一, 第13行"穑民用章"的"章"字泐失,"韩林"的"林"字完好。纸墨精良,字口清晰,为难得的精拓本。有张穆跋并"阳泉山人"、"殷斋居士"、"石州审定"等藏印。原为刘宝楠手拓后赠给梅伯言(曾亮),伯言又赠与冯鲁川(志沂)。现藏故宫博物院。
  
  《封龙山颂》碑为汉延熹七年 (164)立,原在河北省元氏县王村山下,道光二十七年(1847)被元氏县知县刘宝楠重新访得,移置城内薛文清祠。据传,移置时运工嫌其重,欲截为二,剥凿时碑裂为 4块,虽经嵌合,裂纹依然可见。碑文隶书15行,行26字。碑侧有唐咸通年题名,因字已漫漶难辨,故多不拓。
