2 Groschen small shield, grey ultramarine, peculiarity "strong vertical perforation.", this running through the image of the stamp, offset by approximately 2.5 mm to the left, and therefore cut from the sheet with scissors, cancelled with NDP single-circle postmark "Luetjenburg 21 3 72" on a postal fragment, flawless cabinet condition, such strongly perforated values are rare, as the final inspection at the Reichsdruckerei usually sorted them out. Photo certificate Hansmichael Krug BPP "in flawless condition."
