Hello Vladimir,
I am sorry that I apparently did not see your note that you don't want German stamps from before 1992. Looks like most of the stamps I sent are from 1991. I certainly could have found stamps from 1993 onwards. Do I understand correctly that German stamps after that years are okay for you?
Regarding the two damaged ones, they were certainly intact when I prepared the letter. I don't know what happened to the letter.
I will sent you a substitute letter with slightly newer stamps to compensate this disappointing experience. Wishes can often not be fulfilled by random swap partners on mintstamps.club, so you will have to accept this, but in this case, it was clearly my fault.
Regards
Markus
