What’s your equivalent of Becky’s manhole cover?

“I’ve walked down the same street so many times but hadn't spotted it before. 

Later, I found out that it’s a coal hole cover, where coal deliveries were made into the cellars of houses. It turns out this is one of many decorative coal hole covers in the area.

Once you’ve spotted one, you start to see them everywhere.

Over the next few years I got a bit obsessed with manhole covers and coal hole covers. If you search the term in my phone you’ll find hundreds of pictures of them from around the world.”
