..that went on service? Take a look on scans a friend of mine send me. He bought the original in an old book store in holland (his mother works in a library and digitalized the A2 size map for me on a machine, that is for digitalization of old charts and maps for storing!). She was astonished to see such a rare document.
Now i am not sure, if this could be true. In other words: I cant believe it! There are several markings on the map! Look at the front side...there are relics of pencil markings. and on the back there is an (water caused?) imprint of a pencil drawn movement chart!!!
Could this be true? Would be great stuff! If you think it is worth it, i will let his mother make a high resolution scan (costs some more money!) and reprint this map in original size for sale. What dou you think?
