9 Kr orange yellow numerals issue 1860 as a single franking on registered letter to Magdeburg cancelled by clear centric mounted four ring cancel "220" ( = Frankfurt on M. ), arrival postmark mute single circle at back, the stamp point at the as usual cut on: with wide margins at the right side, very close margin to full margins and partial cut into to the remaining sides, all in all a superb cover, not least because of the optical effect (yellow stamp on blue background)
