Note: The sheets of 100 were overprinted in settings of fifty, thus each sheet went through the press twice. On one complete sheet and the upper half of a second the overprinting was in red, then it was decided to re-overprint in black in order to be more visible. Therefore this is one of ten possible se-tenant pairs.
