Every kitchen when I was a kid used to have a dartboard on the wall. With zillions of holes on the wallpaper around it.

Stone fireplaces with a hole for the huge VHS / Betamax video to slot into... just below the wooden plinth where the tv went. The epitome of sophistication.

Formica (in general).

Wood paneling on walls.

China Cabinets. EVERY house had one. Some still will... but EVERYONE had them.

Polished brasses on the wall.
