A little i've found about the cover. Obviously it's san fran's skyline, but i think it's an older picture due to the foreground being undeveloped land. It was taken from across the bay at either that airport type thing on alameda island, or from bay farm island (which is now all residential)
Also that tall building in the middle of the pic (not the TRIangle shaped one)?
555 california street
Edit: but the triangle shaped transamerica building is 345 california center (sequential numbers, adds up to 12, multiple of 3, etc)
