A fine used example, neatly cancelled by large part Bathurst circular date stamp, dated "20 SP 35", which leaves variety clear. One slightly pulled perforation at top, but a very scarce printing variety in used condition. The total printing was only 787 sheets, probably from six vignette plates. Stanley Gibbons catalogue
