France – Second Empire issue 1f, one glass support cliché with a beautiful tête-bêche pair, image reversed, in an enticing greenish-blue shade which is most unusual for a Sperati item, also one paper with a trial print of partial cancellation numeral 73; a production item of the highest rarity and one of just a few tête-bêche clichés on glass from this issue, here with the accompanying cancellation.
