…that GDR Passports (East Germany) issued in the last days of the country were still valid till 1995?
Even the German Democratic Republic of Germany was obsolete since 3 Oct 1990! That sounds strange and I believe there was no other case like that when it comes to passports. But the reason was simple. These “extension” was based on German law as it was impossible to issue for millions of new German citizens new documents in such a dynamic time. So if you are lucky you can find a GDR passport with visas or stamps from 1995. If so – keep it as this is something rare!
