the "1950's rotary phone" looks more like a 1980's version. The 1950s version had a metal dial attached to the mechanism with a nut, and the round designation logo snapped over it with a couple of hooks. The plastic dial with a small hole to remove it came much later.
The 1980s "Typical" phone looks more like a hotel phone than a home phone. Very few (if any) residential subscribers had the red "Message Waiting" light.
The "GSM phone" looks more like the in-car vehicle mount versions of the analog cell phones of the day.
And it's interesting that most residential cordless phones, and niche market phones like the Mickey Mouse phone or the Football Phone are completely ignored.
