How the hell did this happen?

I'd initially planned to post something on long term queen sacrifices this evening. To this end I was trying to search my database for games where one side was up a queen for an extended period of time (20 moves or so) but still managed to lose. Turns out I couldn't find any real games like this, mainly because I could create a search filter that returned games where Black met this condition, but couldn't do the same for White. I did actually find 3 'supposed' games where this happened, but in each case it was simply an incorrectly recorded result (ie Black won but it was recorded as a white win).
However I did run across the following position from the 1931 Olympiad. I am impressed by both the arrangement of Black's pawns, and how useless they turn out to be. How this came about can be found in the following game.
