Years ago, you could buy wallpaper for your house that was photographs of various things. There was one of a tropical beach, and a shot of Earth seen from Lunar orbit, to name but two. They were kind of cheesy looking for the most part, but the one of the Earth, would look great in my planned living room, so I’m wondering if it’s still sold, and where I can get it.
Yeah, they’re still available, I had a jonesing for a interesting wall treatment a couple of months ago and researched 'em. They’re still incredibly cheesy looking
