Does anyone know what were popular prints/pictures on people's walls in the 1970s? We are buying a house built in the late 60s and furnishing it with a mix of 1960s/70s G Plan/Ercol stuff and some 'retro' but modern pieces. I've even bought my macrame pot holder 
We have a massive world map which we'll hang in our living room but am a bit stuck as to what to hang in the dining area - what would have been typical of the period?
