The 1895 1d Burelé band issue, like many of the Sideface issues, has a number of frame flaws found on the outer edges of the various moulds. These flaws probably occurred when the copper shell was stripped from the mould.
Because frame flaws occurred before the printing process they are constant flaws and can be used to assist in plating this issue. To illustrate this I have analysed positions 15 and 97 in the sheet, using 4 examples from the 4 sheets in my possession
