“Ghosts of Amsterdam” is a fascinating site, the work of Jo Teeuwisse, a Historical Consultant in Amsterdam, who superimposes World War II photos of Amsterdam over modern photos of the same places
Years ago I found some negatives in a fleamarket. I scanned them and put them online. I then found some of the spots in the photos and took pictures there. The picture below is of the Liberation Parade on Friday June 29th, 1945 in the Vijzelstraat, Amsterdam.
