I couldn't help checking out the other items, and a lot of them seemed to belong earlier than the 70s. They might have still been prevalent in the 70s, but started sometimes long before. The one that particularly surprised me was the telephone, where they claimed most had just the one wall phone. By the mid 60s I had a princess phone in my room. It WAS still the same line, so only one person could use it at a time, but it wasn't just the one wall phone, and they are talking about the 70s.
