We are all Jock Tamson's Bairns

Have been noticing this one for a while. It's on the cycle path at Leith. This morning, cycling out to Comely Bank for work on a glorious day, I was ahead of time enough to stop and snap it.

It's a Scottish phrase I like - 'we're all the same'. I first came across it seeing a play by Liz Lochead in Glasgow, I think at the citizens but I'll have to go check.
