If you scan it, you can use it as an overlay in Google Earth (you have to fiddle about a bit in Google Earth to locate, rotate and stretch the map to the right scale and orientation). It can be helpful when you are trying to show how different it was "back then" (e.g. a farm in what is now a housing estate). When you are displaying an overlay, then a slider bar appears at the bottom of the Places menu to control whether you see the normal Google Earth image, the overlay or (the best part) a blending of both which is useful for comparing the differences. Here's an overlay I experimented with, showing part of Brisbane in 1943: http://www.chapelhill.homeip.net/FamilyHistory/Photos/test/Brisbane-1943.kmz Kerry

You're giving me some great ideas. Many thanks! Mardon
