This mailbox comes from the children's camp in Molinos.
The FECSA employees children had the chance to spend a fortnight there during the months of July and August.
Children at the camp were able to write to their families. They posted the letters in this private mailbox, where they were collected by the public mail service.
On the last weekend of the camp, the children were visited by their parents, and those who wanted to could go back home with them. Children who were not picked up by their families had a bus service that took them back to their home town.
