I think it&#x27;s fair to say that Anatoly Zak did it. I&#x27;ve never seen it before, but look at all the renderings on <a href="http:&#x2F;&#x2F;www.russianspaceweb.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.russianspaceweb.com&#x2F;</a> (browse around).<p>I would even guess that he shopped around first printing of it and they picked it up, that they didn&#x27;t commission it.
