That is no 'average' 60s kitchen!!! I was born at the end of the 60s but lived in the same house my parents got married & moved into until 1975.
Our kitchen looked nowt like that. Mind you - we lived in a slum clearance terrace in the scrag arse end of Salford, not the leafy suburbs.
A dinner party was a takeaway from the local Indian or Chinese and a Party Seven & Babycham or summat!
We did have a fridge though. Courtesy of the catalogue.
