...after JFK, they stopped using open cars to protect the President... so no doubt Ronnie stressed out the secret service when he used his sunroofs like that! I'd have to look it up, but you'd think if this was after the assassination attempt, Reagan wouldn't want to put himself in harm's way like that.
Actually, it's clear that the Reagan postcard shown earlier is from his 1981 Inauguration. It's also clear that he's riding in the old Lincoln limo that was part of the Presidential fleet at the time (prior to changing to Cadillac in 1983.)
Here's a similar (yet different photo) of the event. You can tell by the clothing and some other details that the postcard and picture were taken at nearly the same time:http://www.history.com/topics/us-pr...gural-parade
Also, checking out the earlier posted link about Presidential limos, it's interesting to note that:
The Lincoln was used by Presidents Ford, Jimmy Carter and Ronald Reagan; it was the limousine that Reagan was about to enter at the time of his assassination attempt in 1981. Ironically, the vehicle's armor proved a crucial factor in causing Reagan's gunshot wound - the president was not directly hit, he was struck by a bullet that ricocheted off the armored side of the vehicle.
