When I saw it I immediately knew that it was based on a real ending, but for the moment, I cannot remember which game it came from. A position search in chessbase failed to find anything, but that probably means the arrangement of non critical pieces (the pawns on the kingside) don't match.
What is important is how Black forces through his pawn, sacrificing a rook and bishop, before ending the game with a seemingly quiet pawn move.
