Me, at 21 years of age in 1969 at Kotta, Victoria.
I can assure you that it is 1969 and, if you look real closely at the shed in the centre you will see the rear end of a 1969 Datsun 1000, 4-door. It;s a scan of a Polaroid (remember them?) photograph that apparently proved appetising to some silverfish or similar. I'm sorry to say that it was taken 51 years ago and it lay in a drawer for most of those years.Not to cast aspersions on your venerableness but that picture looks more 1869 than 1969.
