This book is a reference catalog for illustrators, historians, writers and for all those who are passionate about history. As an illustrator, I usually spend a lot of time gathering material for the realization of works, technical details, their characteristics, etc. For that reason I decided to organize several informative catalogs about airplanes, tanks, uniforms, clothing in general, hairstyles, historical maps, footwear, ships, etc. In this way, I hope to facilitate the work of my colleagues, or at least to have satisfied the reader's curiosity to some extent.
