1881 (March 24), folded letter, Klissura origin notation in manuscript, franked with two 10pa black & green, cancelled “X” in black pen and tied by blue circular grid cancel, to Plovdiv, with neatly-struck “Post Plovdiv” Russian-type arrival backstamp (Mar 26), Karlovo c.d.s. transit (Mar 24) on front, a remarkably fresh entire with tremendous visual appeal.
