1 / 3 Sgr. On gray brown, having bright colors, attractive and very rare block of nine with sextuple mounted four ring cancel "300" from Hamburg. To the visually better effect were right and at the bottom the margins mostly added to, above likewise, there including small piece image supplement. For this purpose the unit has been detached from the base, a smoothed cover crease can not be excluded. Except this block of nine is us another on cover from Hamburg to Blankenburg known. Blocks of nine count by of this stamp as the largest known unit, expertized Pfenniger, sentimental value!
