Do you have a link to a higher resolution version of the photo? It looks like there is a sign of some kind hanging from the running board, but I can't make out what it says.
Are we looking at a Model K roadster with a M.I.L. seat?
Yes, and I think the sign reads "Ford 6 Cylinder". Then possibly "$2800."
I suspect this is a Ford dealer with a Ford sign under the running board. Other Ford Model K advertising included Ford signs attached under the running board:

Thanks Rob. That hood looks long.
