No, it’s not upside down. This wallpaper is the reason I could never have Chinese friends or colleagues over to visit. Aside from being unbelievably tacky, yes, it’s upside down.
I really can’t imagine what the people who owned this house were thinking.
A rental property I lived in years ago had one wall covered with weathered boards that looked like they were salvaged from an old barn. The boards had rust streaks that obviously had dripped down from old nails — and had been fastened to the wall so the rust streaks ran upward from the nail holes. It bothered me.
