Note: The surcharge was applied in a forme of 25 (5x5), four times to each sheet, with the well-known erro, inverted "s" in "cents", falling on Nos. 15, 20, 65 and 70. In this case, the error on No. 65 appeared in its normal position, but on No. 70, it fell on the gummed reverse of the selvedge. When the printer applied the hand-held "s" to No. 70, he did it the right way up, not being aware of the error in the surcharging forme.. . provenance:. Patrick Cassels, October 2003.
