As an illustrator and historian, I have found that there is a lack of material collected to facilitate the work of illustrators, historians, writers and to satisfy the curiosity of all those who are passionate about history. A lot of time had to be devoted to the search and selection of material, which was generally dispersed in numerous historical sites and documents. That is why I decided to organize several informative catalogues on airplanes, tanks, military uniforms, civilian clothing, weapons and ships. With this work I hope to have contributed to simplify the task of many professionals.
