Went looking for the rant board today but sadly nothing was there.
I went past the other day and was delighted to see one remaining piece still in place.
It is on the left hand side. It is about A4 in size. Framed in wood with a plastic clear sheet to prevent weather damage. It protects a hand drawn picture (felt tip pen on paper) and captioned with “Carbon footprint and sink”. I make out that they have drawn a footprint inside what appears to be an old fashioned laundry sink. It is screwed to the chipboard with eight Phillips head (crosshead) screws. Two in each corner for good measure.
If you look carefully at VictorianNoah’s third picture in post #8 above, then you will see on the left hand side the corner of it. (Thank you VictorianNoah for taking those pictures and posting them in 2009. You have preserved an interesting bit of our local history. I still love your term, “…like something out of a fever dream.”)
