I checked megabase 2012 and don't see a game listed between the two players. If chessbase doesn't know about it, it must have never happened! ;-)
Game by Marco vs Salter

I'm not even sure who M. Marco is. The one that died in 1922 is Georg Marco.
EDIT: His brother apparently.

Michael Marco – J. Salter

I was reading Yusupov's book: Build up your chess vol.1, the fundamentals, and found at page 15 this example based on game by Marco vs Salter, played in Czernowitz 1929.
I believe the year is wrong, because the Salter player I found was already dead, and the games I have of Marco in my database are up to 1922. Does anyone have the correct game in PGN format?
