T&E and Telephone Cables

Interesting themes for this month's Mono Monday - this is my take on cord or cores.
The telephone cord is four core - and quite thin ones too.  Used for putting in telephone extensions - remember those?
The mains cable behind (Twin & Earth) is rather bigger. Used for wiring up the sockets in a house.

I've put an orange filter on in Silver Efex to get the sleeving around the earth to stand out. 

Edit: look carefully and you'll see I nicked the insulation on the neutral, won't be using this piece.
