Hi Ian, this is exactly the right place to post these lovely old photos for dating...the problem is that evidently, we don't seem to have much of a clue at the moment

I downloaded the top photo and have been searching for one dateable lady's dress, but they're all men at the forefront. I can see a couple of ladies' hats though, and the general feeling I have is that the photo is earlier than 1935...maybe 1910ish. Just a feeling, and my own opinion, and hopefully someone else will be able to pin it down. You'd think the car might be a clue, but from the photos of vintage cars I've been looking at, styles don't seem to have changed much from 1910 to 1935

What is that thing with people piled on it on the left in the top photo?
I'd like to see a scan of the entire top photo including the corners, if possible, and in colour please.
Is there anything printed on the back?
Cheers,
China
