The rarest variety of Danzig Orta 1656.
Variety not described in the "Catalogue of Danzig Orts" (Parchimowicz, Wiącek, Brzezinski). In Igor Szatalin's catalog estimated at a very high degree of rarity R7, illustrated in his museum piece (MNW).
Ort with titlepage started IOA (instead of IOH or IOAN).
First time in our offer, and probably the first time in a stationary auction in Poland.
