While studying thousands of used issues, I discovered numerous unlisted plate and printing flaws that had never appeared in the Michel catalogues. Each stamp in this lot was carefully selected and individually expertized by Ludger Hovest, confirming its authenticity and variety. This lot is more than a collection — it is a philatelic documentation project, offering insight into details often overlooked in traditional catalogues.
