United States – Providence – 1846 Postmaster’s Provisional, two clichés on film exhibiting a very clear design in red and black, both with observations by Sperati including in the later a 6% of a chemical element used in the process, the other indicating that it was ‘re-issued’ February 1951, a unique duo, with only an unused reproduction and no proofs of any kind in the “Ultimate” collection.
