Auction 333-341 Europe & Overseas Americas (North, Central & South America) - Day 1

1867: Perforados, "COLUMBUS HEAD", "DIE PROOFS" of all five values including the Master die, printed in black, stuck to carton. The proofs bear the internal reference numbers 323 and 323 A through 323 C. The 2 c. value also displays a reference 330 and the 323 reference below, as if the 2 c. had been on a separate order and was linked to the other stamps by a reference underneath. Given that this was issued earlier here is a proof that it was treated differently by the printers.
