So I absolutely applaud this type of book paper !! I would like to see more of the same type! One commentator wrote that he especially interested people who lived through that period, this is incorrect; on the contrary! I was not old enough to have lived through that period, no one around me, gold, the book we wonderfully immersed in the heart of that period; I applaud this original idea to hide almost every page, a letter, an envelope, a booklet, a memory, a leaflet, a poster; it's so well done that it seems to have in the hands the original. Some documents or letters are really moving. This is amply illustrated, somewhat playful, visual, and gradually we are immersed in this atmosphere. Book to recommend to all young and could also be used for high school students for another approach to history .......... Excellent support !!
