Hello all, really enjoyed reading through this site and have some questions!! Below are some scans of marks I have on some of my covers and would like to know if anyone can help identify them.
This is M.Jantzan on the back side of cover
This mark I have been told belongs to a Dr. Syndikus Ernst Wolff, that is all I have on this though
Some kind of signet, not an INFLA-Berlin one though
Another signet that isn't from INFLA-Berlin.
If anyone can help identify these, I would certainly appreciate it!!
