Does anybody recognize this position?

Hello.

This position is from Reinfeld's "1001 Brilliant Chess Sacrifices and Combinations" no. 800. Feels like a position from some actual game, but I can't find it in any of my game bases. Could it be an analysis from a game or? Hope some one can help me!

I don't recognize it, but I have a database.

34.Rc7 (a decoy based on Rf8 mate)

34...Rca8 35.Rbb7.

Thanks!

Euwe...knew it was some world class player! Like the variation 34.Rc7 Raa8 35.Rbc3 Rxc7 36.Nxc7 Ra1 37.Ne6 +-! Some sort of double double attack!

Oh wow, that is nice, I saw Raa8 but I didn't realize the solution required more calculation.

Beautiful combination indeed.
