I love stories of paper treasures being discovered under floorboards or in walls of houses, from ebay seller golden-age-comics:
In 2015, under the floorboards of a shop in a seaside suburb of Adelaide, a treasure-trove of comics was discovered in a cellar not accessed since just after World War II. Previously, the shop had been run as a news agency, and the cellar was utilised as a storage room. There were piles and piles of comic books, newspapers and magazines, in immaculate, never-before-read condition.
