Two hundred years already, eh?

<February 1885, page 46:
‘When I first met Anderssen in 1862, he spoke in the highest possible terms of Morphy. ... In 1866 I had another conversation with Anderssen about Morphy. The professor had much cooled down in his enthusiasm, and he did not seem to think that Morphy could always have beaten him for certain. My own impression is that Anderssen, who could not play a single game blindfold, was at first overawed by Morphy’s wonderful sans voir performances, and he overworked himself by calculations out of his real depth. But he subsequently found that he could hold his own against blindfold players like Blackburne, Paulsen, Suhle and Zukertort, by relying on his natural fine judgment, and then he began to doubt whether his fear was based on real grounds.>> Paul Morphy (kibitz #6932)

Is it really conceivable that Anderssen couldn't play even one game blindfold? Can anyone identify a game, occasion or source to the contrary?

Blind games by Anderssen are very rare, but <Steinitz's quote isn't true!> ... - an example of Anderssen's 'sans voir skills' was given on page 13. at Bird's book 'Chess Masterpiece':

Harrwitz vs Anderssen, 1848

.

Comments by Henry Edward Bird:

20. Ng3 [Well played.]

25. Qg5 [If the Knight is taken by 25. exf6 the piece can be regained with Qe3+.]

29... Ne3 [Ingenious and perfectly sound, in fact, practically deciding the game in Anderssen favor. This interesting and excellent game, played by both without sight of board and men, would be considered a masterpiece if played by any two players with the board and men before them.]

Another game was published at the 'Schachzeitung 1849 Vol 4' on page 141 (both played sans voir):

Eliot Hearst & John Knott - Blindfold Chess, p. 29:

'Anderssen occasionally played blindfold chess, and once he played against the sighted Kieseritzky at Simpson’s Divan in The Strand, London, in June of 1851, just after he had beaten Kieseritzky in the first round of the international tournament. Kieseritzky gave a pawn handicap and allowed Anderssen the white pieces and two moves at the start of the game. Perhaps Kieseritzky felt he had achieved a measure of revenge after his loss in the regular tournament, because he won this struggle despite the odds he gave. On the other hand, Anderssen played blindfolded while Kieseritzky did not.'
