historical Map overlay?

[Cen]

Hi all, New to the forum, but have read it for years. I've got an Etrac and was reading someones post last night that they can use Google earth or Bing maps and overlay historical maps over current ones. Does anyone know if you can do this and if so how? Also any other sites with older aerial maps would be appreciated. thanks and Happy New Year. :confused:
