How many did he do?

Even after all these years I still see the occasional album cover by Roger Dean that I don't recall having seen before. Roger Dean did many famous covers for Yes, Asia, Uriah Heep, Greenslade, Budgie and many other bands in the seventies and onwards. How many? Who knows? Maybe he doesn't even know himself. If you are a fan opf Roger Dean or the bands like Yes, Asia or Greenslade or if you have no idea what I'm rambling on about and would like to see on the basis that a picture is worth more than a babbling blog then click here.
