There's a book of John Wesley Powell expedition photos down the Colorado River in 1869, the first time it had been explored through Cataract, Glen, and Grand Canyons. The authors returned a century later to retake the same photos from the exact same vantage points. It appears there are quite a few then and now books available for various other interesting places in the world. But yes, Street View for the past would be amazing. Maybe a few photogenic cities like London or Paris could organize enough period photos to build a pretty good approximation. Would make a nice History thesis project to organize all the available findable photos for a neighborhood at a particular time. The book is called _In_The_Footsteps_Of_John_Wesley_Powell_ by Stephens, Shoemaker, and Powell. It appears to be out of print but good libraries should have it and there are used copies online.
