I am trying to find information on Margolinas lithography in Kaunas. I am interested in what sorts of paper they used, where did they get it... I know that some stamps were printed on wmk paper and some without. Was there any research published on sorts of paper (consistence, structure, pulp percentage, etc)? Most importantly - did they print stamps for anyone else besides Lithuania and Klaipeda? Does anyone know where I could find such information?
