Stamp booklet 37 Hindenburg 1938/39 without printed serial designation, with booklet panes 89B, 90B, 91B and 92B, margins not perforated through, interleaves unprinted. The booklet corresponds to the 3rd and 4th printings (MiNr. 37.3 & 37.4); presumably the missing serial designation is an accidental printing omission, perfect condition apart from adhesions on the back cover, original staples, photo certificate Hans-Dieter Schlegel BPP (2019).
