The Reichstag in Berlin - a photo taken with my over 60 year old Linhof Technika on 9x12cm film.
If you look at the negative with a magnifying glas you can easily read the license plate of the Volkswagen bus parked there :-)
Its very impressive what that old camera can do!

It still amazes me how much resolution you can get from big film and a good lens.
