This photo was taken in October 1957. Just months later, Eisenhower was in front of the cameras for another milestone — the dedication of NBC’s new $4 million Washington studio, where he became the first president ever recorded on color videotape.

The Lincoln Cosmopolitan was built 1949-54. https://en.wikipedia.org/wiki/Lincoln_Cosmopolitan
The photos published here are the first, and only, I have ever seen of the Presidential Limousine – Bubble Top Parade Car. Has any reader of these pages any idea what the future of this particular vehicle became? Does it still exist, perhaps in a private collection?
It’s in the Henry Ford Museum, alongside the car that replaced it in which JFK was assassinated.
