The Netherlands Photomuseum in Rotterdam has an exhibition "Lust for Life" of Dutch photographer Ed van der Elsken (1925-1990) He is well known for his streetphotos in the sixties and the seventies. In 2016 his colour slides were discovered that were in a bad condition and had inmediately to be restored, 42.000 colour photos were cleaned and saved forever from destruction.
Here an example of the restoration.
It was a joy to see all the photos of the sixties in Amsterdam, the" flower power" and "sit ins".
Brought back nice memories of that time when we lived there too.
I had the same blue shoes with platform soles! And a mini-skirt too.
