Until January 1st, there is a display of 18 Mustangs ranging from 1964 to 2012 in the Den Hartogh Ford Museum (which also has Ts and older Ford models). The article says that the 50th anniversary of the Mustang isn't until next April, but they chose to jump the gun for two reasons: (1) it's winter and the Mustang owners aren't driving their cars, and (2) they will all want to be driving them next April rather than having them in a museum.
If you want to know what the article says, Google Translate does a reasonable job - not perfect, but reasonable.
There was an article on the internet this week about a young lady who bought the very first Mustang and still owns it. There was a nice video also.
