Fountainhead Earth: design geek help wanted.

[reddragdiva]

I need to do an image for the Uncyclopedia copy of that last entry. To this end, I need to know what font is used on this book cover. Or if you know what font it's derived from. Thank you.

Update: echo_echo seems to have spotted its nearest ancestor: Helvetica 73 Bold Extended. Now I would be most grateful if someone with a copy to hand could please help me by rendering the capital letters, numbers and colon, about 100 point (since copying the font file itself would be a copyright violation). Or the font file itself if someone has a suitably licensed copy, of course!
