Heinrich Köhler 384 Auction – Day 1 Single Lots: Europe and Colonies, Kingdom of Lombardy–Venetia – The "P.G." Collection

1880 (March 11), registered cover from Tatar Pazardjik to Adrianopel, likely paid 1-1/2pi letter rate plus 1-1/2pi registration fee, struck FRANCO in black due to unavailability of postage stamps for prepayment, neatly-struck Plovdiv transit on front (March 11), reverse with faint c.d.s. arrival backstamp, some toning, cover reduced at right, yet a scarce example of registered mail from this short-lived period.
