A few weeks ago, I was asked if I had any pictures of chimneys.
Digging through my photos, I was amazed to discover that you could count the number found on one hand's thumbs. Since then, I've become a little obsessed with photographing tall stacks.
One of the more unusual is found in Wolverhampton - this square (and very modelable) structure appears to be made out of a pile of concrete cast squares. I'm sure I used to have something similar in plastic as a toy many years ago.
I'd say that while it looks modern, it might date back to the 1970s, but would be happy to be corrected by anyone who knows more. I'd also be interested to know if it's unique.
