The Cross & Cockade International is the quarterly publication of a non-profit organization known as The First World War Aviation Historical Society. The UK based organization has been publishing these journals since 1970 with the objective of furthering the study of First World War Aviation History. The Company overview on its Facebook page says “Cross and Cockade International can trace its history back to the 1960s. We have always attracted some of the premier historians in the field. Our current President is Air Vice Marshal Peter Dye (Rtd), Director-General of the RAF Museum. We publish a high-quality quarterly journal of original research into the subject.”
NOTE: The journal is apparently not available as single issues, but by volumes. Back issues sell for $33.50 per volume.
