Veery nice! Thanks for sharing
Historic sketches of blindfold chess exhibitions

Thanks for gathering up all those images.
Note: the only one wearing a blindfold is Philidor.
Here's a photo o George Koltanowski giving a blind demonstration on Jan. 6, 1945 against only 7 opponents (Alfred Barr, Jr., Max Ernst, Frederick Kiesler, Julien Levy, Dorothea Tanning, Xanti Schawinsky and Vittorio Rieti).Kolty is facing away the wall. Alfred Barr, Jr. in on the extreme left across from Marcel Duchamp who is making Kolty's moves. They're using a Max Ernst set and Strategic Board. On the right is Xanti Schawinsky using a Bauhaus set.

Alekhine and Kolty played simultaneous tandem blindfold games against consulting opponents (form "chess Review" April, 1934):

Paul Morphy and Louis Paulsen played each other blind on on October 10, 1857. Actually, Morphy was selected to be one of Paulsen's 4 opponents in a blindfold demonstration. Paulsen was a noted blindfold player. Morphy asked is he could also be blindfolded. This was Morphy's first public blindfold game and the only one recorded in which he played the black pieces. When Morphy announced mate in 5, Paulsen, in a minute or two said, "I can see it."
Below is an artistic rendering: (Morphy on the left; Paulsen on the right).

Well, it was @introuble2 who provided the format and the original intriguing images. I was only giving it a boost.
I thought I had posted this one--- as a tie-in to the Kolty - Alekhine story:This is Alekhine giving a simul, date unknown.

Here's another blindfold simul by Alekhine, against Nazis

No discussion on the blindfold can go without Newell Williams Banks who once played simultaneously chess, checkers and billiards.
"Banks played his first game of blindfold checkers at age five years and six months at the Detroit Chess and Checker Club."
"Mr Banks has traveled over 1,000,000 miles in the past 45 years and played about 600,000 checkers and chess games. During this time he has played over 80,000 blindfold games." Edward Winter

Mikhail Chigorin
info obscure:
I've tried to OCR the Russian text and google translate it but with no much of success. I've caught only that it was possibly about a blindfold exhibition with 10 boards at St. Petersburg Chess Club, this year [??-so for the period Jan to Apr 1888]. However Chigorin's ability to play 10 boards blindfold is generally mentioned also in ICM Dec 1888, p.356.
