Argentina 1935-51 Definitives

I have been studying these definitives since approximately 1993. I find them to be very challenging to study, given the gaps in knowledge missing even from the most advanced Argentinean specialized catalogs-e.g. Klass 1970 and Kneitschel 1951.

I hope you are interested in collecting them/studying them. I used to host a lot of information about these stamps in a web site, and now I am hosting it in a YouTube channel:
