Vintage shelf liner Orange Brown 4 Rolls unknown brand vegetables kitchen

This is a vintage shelf liner with a pattern of vegetables and fruits. It is in pretty good condition and there are 4 rolls in total. However I was scared to unroll them all. Didn’t want to damage. Don’t know how they adhere…water? Paste? And don’t know the exact amount but tried to show some of the rolls spread out. I thought it was wallpaper #vintage #cottage #food
