I kinda like the "Compagno Di Sbronze" cover, although it does play a lot on the Buk image.
I also liked the cigarette smoke becoming an image of Buk on the "Storie Di Ordinaria Follia" cover, but placing a rose between the girl's legs is'nt exactly a new idea. That's a pretty old one, in fact. Placing some other kinda flower, or even a cactus, would have been more interesting.
The cover for "Musica Per Organi Caldi" seems a bit weird to me, because I can't see Buk wearing an American flag or be interested in it in any way, shape or form. He was never a flag waver, i think.
