Collection Bizone Band Upper Edges LUXURY !!!

Dissolution of my own quality collection "Bizone Band / Netz imprints on No. 36 - 51" in top quality! I have always attached great importance to absolutely perfect preservation! Here the upper margin collection stamped band overprint. Contains better colors tested on ArGe, the 37b W OR with BPP findings Schlegel and the 41b P OR sign. Schlegel BPP. For a color check it would definitely be worthwhile, at least the card with the upper margins 37 P (possibly e) + W and to have the letter checked with the 43 Pdgz (quite sure d), since I had actually not gotten to it yet! No. 46 P dgz and the letter with the 48 P are both deeply signed Schlegel BPP. All upper edges are not pre-creased and not separated! The total catalog value according to MICHEL 2021 is 3493, - €. Only the simple upper margin evaluation, without the corner margin surcharge etc., was calculated! I give a guarantee of authenticity and inspection on all pieces in the collection!
