Las Vegas, September 1963, Shep's New Painting

I took this photo when I was 16 and I've always wished it was in color.  Now I can make it so, but this has brought up a whole set of new problems.  What colors?  I've had to do pretty extensive research to find out what colors go where, and exactly what are the names of the Casino's.  I blew up the photo to 8" x 8" and still can't see all the details.  There are many details in this painting I really like, but a few I'm IMPROVING on...the cars.

If you click on the picture and look in the center you'll see two cars from my past.  Can you tell what they are?  Here's a hint:  Mitt Romney's Dad was CEO of the company that made the red and white car.  Have fun guessing!
