It is easy to find two games defended by Emanuel Lasker, in this line, from a mondern games database but neither appear to be the game referred to by the Pittsburgh Press on October 18, 1906.

Recent correspondence with chess historian John Hilbert confirms the outlines of the Pittsburgh Press story - the simultaneous exhibition, the location, the city, the date, Lasker's opponent - but, alas, not the game, itself. To that, Richard Forster, who co-edited Emanuel Lasker Volume 1: Struggle and Victories: World Chess Champion for 27 Years (which, by the way, included Hilbert's chapter, "Lasker: The American Views"), unfortunately can add nothing.
It is the old story: defeat the master, and submit your game for publication; fall to the master, and keep your gamescore to yourself.
