It should be the header (3 men sitting in a train)
Where is this picture from? I've seen it quite a few times but what's the meaning behind it?

It's a still from the film Quadrophenia, showing how uncomfortable the leading character played by Phil Daniels is with the rest of the population!

If you had seen the film, you'd know what I mean!
