Name of painting on cover of Shelley's Frankenstein?

[Mike]

I finished re-reading Mary Shelley's Frankenstein a couple of weeks ago. I returned it to the library, and have been curious what the name of the painting displayed on the cover is. I can't remember what the edition, year, etc. of the book is, but perhaps one of you can help me out (sorry if the description isn't clear).

The painting shows a man dressed in black with his back towards us (if you're looking at the cover of the book). He's standing on a cliff or mountain of some sort and looking out or down into clouds.

That's about all I remember. I'm not even sure if it is a famous painting or just some cover artwork, but I figured it was worth a shot.

Thanks for all your help!
