Make & year of race cars?

[RimrockRandy]

We are so Thankful for this Forum. We don't use it often, but when we do, you've never let us down.  It's so great to know that the people on this Forum will ride to the rescue and identify whatever it is that shows up here.  THANK YOU!

OK, so we have one here that's totally stumped us.  As always, we do quite a bit of online study before we come here.

What are the makes and years of the four race cars shown lined up in Prescott, Arizona?

We know for 100% certain sure that they were not affiliated with the 1914 Cactus Derby that passed through Prescott.  We've searched Prescott newspaper for the years 1909-10-11-12 to attempt to determine if there were any auto races.  There was one proposed for 1909 but it never happened.  There "might" have been a Prescott-Phoenix race in 1911 but we haven't proven that yet.

Judging from various online race car photos, we think these cars are circa 1910-1911.  Other than that, we're clueless.

THANK YOU for your help--it is MUCH appreciated!

Randy, 

 

It might be helpful if you post the photo on a service like Photobucket, etc, in high resolution...and then publish a link here. That way we could go look at a much higher quality version, and enlarge it for details. Personally, I'm not much help on cars that old. But we have lots of folks on this forum who would be happy and better-able to assist you.

Thanks, Randy, unfortunately, that's the highest resolution available from the archive there I found the photo.  I truly wish I had a higher resolution photo.

Could be an automobile race event as part of the 1912 celebration of Arizona becoming a state.
