Numbers 1 - 3 inclusive behind the Hubmobile are horse drawn.
What are numbers 4 and 5? If it's too small an image, go to Shorpy, Memphis, 1910.
Actually, it looks like #2 and 3 are horse-drawn and #4 is a 1909-10 Ford Town Car or Landaulet. Perhaps the same one as in the previous post? Number 5 is horse-drawn. Number 6 (1309) is a small town car (taxi)-unusually small, I think. Could #7 be a Locomobile?
