1920 - 1999, very interesting collection, the first both years mixed used and unused collected, with some gaps, then but from 1922 except for a few small, not authoritative newer values complete to 1999 in 4 Lindner printed form albums. As well are the years from 1924 except for very few, small values in mint never hinged condition! From here are all good and sought-after issues from the 20s and 30s years mint never hinged included! So complete can this area at rare intervals once to be on offer.
