Hello, I am selling the paper map shown in the attachment. This is a rare time zone map, published around 1920/1930 by the publisher "blondel la rougery" in Paris. It measures approximately 108cm in length and 71cm in height and is in used condition, folded, pin holes and at some folds, small tears at the edge.
