This is one of the best pre Model T Ford advertisements I've seen. It looks like a photograph of both Models K and N. The ad appeared in the February 1906 Motor magazine. There were over 80 different makes of cars advertised, most with full page ads like this. Attached are a couple more, along with a link to all the cars advertised in the February issue.

A couple of competitor's advertisements:
It's interesting to see how different automakers choose to display and write about their cars. Motor magazine seems to have had very good advertising capabilities,,and claimed to have the highest number of readers of all the car magazines.
Hope you enjoy,
