"damn iconic looking" : that's the way Aliz caracterized The Psychomodo sleeve.
And it is indeed.
Why that ?
Steve Harley's look of course, but a bit more than that. It is essentially due to the talent of the man who designed and shot : Mick Rock ! "the man who shot the seventies" as they say.
He also contributed to the Timeless Flight sleeve as far as I remember. May be more, I don't know.
If you want to see all his fantastic pictures, Debbie Harry - David Bowie - Mick Ronson - Iggy Pop - Thin Lizzy and more more more, have a look here :

I recommand especially the Black & Whites, Glam ans Classics. There is also a very emotional section dedicated to Syd Barett.
Enjoy !
