1919 POSTA CESKOSLOVENSKO OVERPRINTS (B.330)
These were emergency stamps? Was there a shady history behind their issue? Which ones are genuine? The different types? Can they be plated (...yes!) The legendary Roy Dehn explains all, but only from the perspective of genuine stamps. It is a technical work, but explained clearly. It does also give general advice about forgeries, but not in detail, the subject is quite complex. An excellent manual for the technical philatelist wanting to study these overprints in detail for the many different (genuine!) types. Czech Society monograph #3, 1985, black/white text, colour cover, 47 pages
