An awesome Chicago penthouse apartment that’s like a museum of 1970s home decorating just hit the market. The three-bedroom, two-bathroom apartment has obviously had just one owner since it was built in 1972. But what’s most amazing is how immaculately preserved the quintessential 1970s home furnishings and decorations still are after more than 40 years. The apartment looks like it was designed by a professional all those years ago, with crazy wallpaper, green velvet everything and even a faux wood-paneled den. Take a step into this penthouse time machine, and experience the grooviest looks right out of a ’70s fantasy.
