Abandoned 120mm films

On 28th July 2011 I found in a demolished area this 120mm. This films were in terrible conditions, full of dried mud, dust ... Some pictures are broken, scratched, erased ... I thought to recover them, who knows, maybe one day I can give it to owners, the powerful of internet era is also about this ...
The pictures seams shoot around '70 maybe Honeymoon ... only one seams to be older: a school trip ...
