The mysteries and treasures of O’Connell Town. 1

For the cognoscenti O’Connell Town is the historic name of an enclave within the larger historic Bligh Estate that once encompassed most of contemporary Camperdown, Annandale, and Newtown. There are no remnants of the Blight Estate left in the area, or so I have been told by a fellow gym user who has lived in O’Connell Town for forty years.
Having moved into this area, while dog walking, going to and from the gym, and to the station and bus stop we are learning about O’Connell Town.
We noticed this display on the corner a few days ago. Take a look.

Look closer. It is an album of photographs blue tacked to the outside of a house. See.

There were twenty photographs of assorted subjects.
Then one day, one was missing but the rest remained. My hands were full and I did not get a picture. Then a few days later they were all gone only leaving behind the blue tack.
Huh? What was that about? You can tell me.
