WW II Map of Hamburg

Are there any good sites where a person can find maps or old aireal pictures of pre or at-the-time Hamburg, Germany; up to say 1945? Dad used to live downtown there until it got bombed. I’ve found some current maps, but some streets seem to have been changed or “deleted” since then. Would like to see where he used to live…

I can not find the old maps on the web so:
