Reconstruction 1946 - 3 commemorative sheets, Province of Saxony

On January 19, 1946, three postage stamps with a surcharge in favor of the reconstruction were issued in the Soviet zone of the Postal Directorate Province of Saxony. Today I can offer you all three values on three small-format commemorative sheets with two different special postmarks from Haldensleben. The special catalog values the stamped individual stamps at € 9.
The three special stamps show: 6 + 4 Pfg, housing; 12 + 8 Pfg, bridge and waterway construction; 42 + 28 Pfg, mechanical engineering, in this case a steam locomotive.
