Other: Unfortunately I don't have this map in my collection yet - however the scan of the cover has been provided to me by Gary Spaid as a reference to the map produced.  Many thanks to Dave Rowlison for providing images of the tri-folds to give a better idea of the over-all appearance of how the covers are incorporated into the design of the map.
