I found the following 2 little cars in there:
They don't make them like that anymore, these were from the following two sets
This was made in 1978 so over 30 years ago by now. I also have the train tracks which were blue before they made the grey colored ones. I had so much fun with Legos when I was a kid and hope that my kids will enjoy these little bricks also. Legos are probably one of the best toys ever made, the good thing about them is that you can use those old bricks with the bricks that they make nowadays, it will never be outdated.
