BASIC CZECHOSLOVAK METER STAMPS LITERATURE AS PUBLISHED in the period of 1926 - 2019
Základní literatura o československých výplatních otiscích publikvaná v období 1926 - 2019
I add that there is quite a number of articles and informtion on www.kf0015.cz, modry.kf0015.cz and www.historiapostalis-etc.cz about meter stamps and connected facts. On all the three webs you may use google translators into many languages if you want to. Especially if you click or tune up category "Filatelie a poštovní historie" or "Databáze ..." or "Osobnosti"and the like.
