1959年香港上海汇丰银行500元档案照片，无论是边框，扭索饰纹，字体，背面银行总行的方向都与最终发行之版别有区别，下方由Saunder及Turner签署。此署名组合从未面世，据资料记载两人仅限于1955-1958年间同时在银行共事，时间短暂。非常有趣味性的一枚，该未被採纳的设计绝对值得研究，‘光头佬’之高端藏家更加不容错过. HongKong & Shanghai Banking Corporation, archival photograph for an unissued $500 design, 14 March 1959, date unlisted noticeable differences in boarder, guilloche, font style, reverse building imaged from the left instead of from the right, previously unknwon signature combination Saunder and Turner who worked together at HSBC from 1955-58,in PMG holder. A previously unknown proposed design with its unusual date and signatures. Interesting and important for any serious collector of the iconic Thomas Jackson $500.
