Two letters, from the turbulent 40’s, a war decade for most of it. Interesting from a historical point of view of course, and they depict a period of which we still do not know as much as we would like to know.
This first one belongs to the espionage area, or intelligence community provenience, if you like.
This second one is a letter from VEF Riga representative in USA, making known the existence of Minox camera to the US photographic market. This letter is issued by the Minox USA, a branch of VEF manufacturer, and includes a few key facts and brief historical background of the Minox camera. Beautiful!
