Here is evidence that beauty is in the eye of the beholder. I've been looking for this, let us be charitable and say "plain-looking," stamp for over two years. It is a D/A Mi 31.
It marks a collecting landmark for me. I now have a complete mint set (at least one -- not all the variations) of all the major Michel numbers for Soviet Occupied Germany, Mi 1 - 3365 and The Official series D/A Mi 1-41.
Why was this stamp so difficult to find? Although Scott references it in its catalog, it wasn't assigned a major number. It is a Scott O39, a redrawn 1954 - 56 issue on granite paper, with one difference. The watermark is 297 instead of the common 313.
With so few people actively collecting this area, I sometimes wonder how many of these are sitting in a WW collection unidentified.
Get your watermark trays out!
