Matheiu Stern is a photographer and a filmmaker who brought to life cat photos of a little girl that didn't want her kitten to be forgotten so she put his photos in a time capsule 120 years ago: "Someone in my family told me about a possible time capsule in our old family house, after investigation I found a box dating from around 1900 judging by the objects and the technic of the photos found inside. I then decided to develop them using one of the oldest ways to make photography prints: Cyanotype", he wrote on his YouTube channel.
