The design is remarkably similar to the issued note apart from the date and the lower right signature and its title. The reverse proof has a handwritten date March-Aug 1973 and is reminiscent of the design for the $100 of the same series, though there are subtle differences in the arches and the emblem at right,the obverse is graded PMG 66EPQ, the reverse 64 (1 pair)
