Social Philately Class is a collecting concept that has existed until recently in various exhibition classes, but it was not recognized as a class for itself. Generally speaking, ephemeris in the collections of Postal history, Aerophilately and Thematic philately contains components of social aspects. Various official documents, postcards, ship and airline companies tickets, postal traffic derivatives and the like not only are suitable for collecting, but often also improved the chosen theme. The framework for including the mentioned material in the philatelic collection is the idea of linking socio-economic history with the historical content of Philately. The goal of Social Philately Class is to present a historical narrative and illustrate the relevance and impact of the postal system in society.
Radiogram is a formalized written message transmitted via radio. It is also known as radio telegram or radio-telegraph message. Radiograms use standard message format, form and radiotelephone and/or radio-telegraphic procedures. The radiogram is transmitted via one or more radio operators all the way to the operator (PTT) that deals with the delivery of radiography content to the destination.
In the first half of the 19th century, the transmission of long distance messages via radio brought great benefits to trade, industry, stock markets, journalism and art.
Philatelistic collections of historical, social and special studies may also contain radiograms – messages transmitted by radio, printed on special radio-telegraphic blankets.
