I know this is a long shot, but I need to match an existing wallpaper in my home. The wallpaper is probably 30 years old. I've searched everywhere and I found some wallpapers that are close, but not exact. I want to wallpaper another room with this same style wallpaper. Attached are pictures at different angles and distances. Even if someone can tell the who the manufacturer could be it would help me. Based on my research it could be a concrete style wallpaper. Thank you
