An atypical (more verbose than normal) example is this one. Most are normally in “Canal and River Trust blue” and say “Pedestrians have priority”. I don’t have a photo, unfortunately.
Some cyclists in the UK have a reputation for “not entirely following the letter of the highway code”. 
well, ish - but i the case of canal towpaths one “landowner” looks after most of it, so signage is somewhat uniform. With other cycle routes across private land, the signage is usually from Sustrans, so again, somewhat uniform.
I can think of at least one public road location where “cyclists should give way to pedestrians on the same piece of tarmac” might be explicitly signed - I’ll have to see if I can get a photo of that.
Edit: Here’s a photo of that public road example:
It’s located here.
