1936 Berlin mini sheet with showing variety double print of the 40+35pf, very fine and post office fresh, the unique example known, this being the discovery item of this error which was only recently found after 85 years since its issue; a major showpiece of these popular issues and a rarity of the Third Reich period with no other double print known on a Deutsches Reich sheet, cert.
