Old Linoleum!? It's hard to see but it is that brown/green marbleized kind. My parents had some in one of their bathrooms and on a laundry table and we assumed it was original to their 1918 house. The stuff may have been made for 40 years so who knows how old mine is. I took out a flashlight and I could see it all along the crack between the upper cupboard and diagonal trim. I JUST about ripped out that 70's diagonal wood but came to my senses and realized it was not a good idea because A. They nailed right through it when they attached the wood B. It might not go all the way to the counter so then what? and C. Despite how much it intrigues me, come on, it would totally clash with my classy orange and harvest gold décor.
