In WW2 information leaflets and posters proliferated. Soldiers were bombarded with Field Regulations, airmen with the latest updates about airborne early warning, bomb sights and radio navigation and sailors with material that helped them identify enemy aircraft and submarines and told them how to operate the new ship board weapons to destroy them. An abundance of familiar slogans exhorted the population to do the utmost: 'Go To IT!', 'Come Into The Factories', 'Keep Calm and Carry On', 'Dig For Victory', 'Lend A Hand on the Land', 'Walk When You Can'. Other messages warned of the consequences of irresponsible behavior: 'Careless Talk Cost Lives', 'Loose Lips Sink Ships', 'Keep It Under Your Hat' and 'Be Like Dad, Keep Mum', the latter illustrating just how much social mores have, thankfully, changed in the last 75 years. This book is concerned with the plethora of printed ephemera that was designed to educate, instruct, inform and entertain. Such original material can still be bought and is easy to store - the posters also often making attractive items for display - but as with all other authentic historical material supply is finite and examples of wartime publications in first class condition command a high price. This is the first time a single volume has been dedicated entirely to a long overlooked component of wartime collectables. It is designed to complement books which focus on traditional militaria such as uniforms, equipment and regalia and is intended to reveal just how much material was produced, across the board, by each of the warring nations. It will advise enthusiasts about what was produced, what is still available and where to find it and, importantly, how to conserve and store such vintage printed items.
