I couldn't find a date on the map, but I believe the map to be around the 1960s or earlier. The map belonged to a friend of mine who traveled there numerous times in the 1950s and 60s.

The map has been well used. It has no writing or stains, but many tears along the folds and edges. 

The glossy front cover is in good condition, but the back cover has a light vertical bend and a dog-eared corner/crease in the top corner.
