I was Googling for information on Kodachrome when I came across this photoblog website, which has loads of great old photographs on it. There is a large gallery of 4x5 Kodachromes from the early 1940s, and the full size versions are fantastic. I especially like this one, which reminds me of my grandmother (who at around that time was serving in a searchlight battalion of the British army, illuminating the Luftwaffe's nightly visits). It is hard to believe this was taken over 60 years ago. Lots of other brilliant images in the gallery - click the thumbnail to see a slightly larger version, then open the full size version with the link in the accompanying text.
