I have created this book as a reference catalog for illustrators, historians, writers and for all those passionate about history. As a draftsman I have suffered many headaches and wasted too much time gathering material for the realization of certain work, its technical details, shapes, etc. For that reason I decided to organize several informative catalogs about airplanes, uniforms, tanks and ships. I hope that in this way I can facilitate the work of my colleagues, or at least have satisfied to some extent the curiosity of my reader friends.
