    You can still access many previous releases of the map tiles in Google Maps if you know the parameters. Or see this site for a demo:

    http://www.econym.demon.co.uk/googlemaps/examples/compare.htm?lat=44.559&lng=-123.2834&zoom=16&one=s10&two=s11

    if that link isgets broken, then this might be better:
