Here’s a chap I spotted at Prêt a Manger in Leicester Square yesterday. He was sitting right in front of me, but I was protected by the fact we were separated by the window, with him on the outside and me inside. I was sitting higher then him, too, so little chance of getting caught out.
Also, like many of the people I end up sketching, he was bent studiously over his phone. Smartphones are a boon to the sketcher: people sit still for ages, staring into them, pretty much oblivious to the outside world. Just don’t try to draw their thumbs.
I was taken by his natty outfit, too, with the matching white cap and jacket. As you can tell, it was a grey late afternoon in central London, and his background was all wet paving stones, but his ensemble marked him out clearly against it. Useful contrast with his black turtleneck and hair, too.
