I spent ages looking at this - it just fascinated me.
I guess it shows which way my perception's slanted, that I saw the Mercury symbol before I saw the Crucifix.
Then I noticed how the cross is emphasized, and that the circle doesn't join the cross at the top. It seems more likely to me now that it's intended as a crucifix, with a graceful halo, and diabolical horns.
I wonder what "HT YC" stands for.
Located on Royal Park Road, on the block of student flats behind the pub. It's about eighteen inches above the ground.
I nearly walked past this one, but stopped for a double-take. Ouch.
It's one of the oddest pieces of graffiti that I've ever seen, alone on an stark concrete wall. Perhaps there's a flourishing community of old-school corporeal punishment enthusiasts in Hull. I'm not sure I want to know.
