@futurebird If it is the real vintage linoleum made with solidified linseed oil (linoxyn), pine resin, ground cork dust, sawdust, and mineral fillers such as calcium carbonate, it's a treasure and ecological. https://en.wikipedia.org/wiki/Linoleum Unfortunately, a lot of so-called linoleum is vinyl or even PVC. And under that you can find everything from mould to forgotten corpses. 😁
