The Barnard College dramatic performances were famous. See, e.g., Omaha daily bee (Omaha [Neb.]), March 22, 1908, p. 18

"'Fair students of Barnard College will appear tomorrow in a "magnificent production of Shakespear's "The Taming of the Shrew." There will be four performances of the play on the afternoons and evenings of tomorrow and Saturday. All of the parts will be played by girls, and the management declares that the dramatic talent at its disposal will make the professionals sit up and take notice.'

So the photos would probably have been taken between April 23-25, 1908.

And presumably, the two characters at the right are Katharine and Petruchio.

"THE SHREW TAMED AT BARNARD, But the Audience Was More Interested In Her Before She Was Tamed.
Shakespeare's shrew was tamed once more in the Barnard College Theatre yesterday afternoon.

It was a shame, too, because the audience was much more interested in her before she was tamed, but this may be due to the fact that the performance took place at a girls' college where they have equal suffrage meetings about every other week. In fact the only reason the play was chosen, one girl explained, was because it has seventeen men's parts, not counting the pages and wedding guests.

But even the most violent woman's righters in the audience couldn't really feel indignant when Katharina finally gave up being shrewish, because a more blustering, bullying, brawling Petruchio never trod the stage.

He swore and ranted as if he had done nothing else all his life. In the dining scene he threw the dishes and furniture around until even those off the stage began to feel frightened, and withal he looked so handsome that people even forgot to laugh at the obvious safety pins which held up his high leather boots.

Lucentio, who wins Bianca, the shrew's sister, ran a very close second to the hero when it came to looks, and Gremio, Bianca's other lover, was such a funny old chap that everybody was sorry when he got turned down.

Of the two beautiful sisters Katharina slammed around the stage in a merry style, but when the more gentle Bianca got a chance to speak she proved herself the better actress of the two.

Moreover, she was the only one in the cast who read Shakespeare's lines with any degree of correctness and beauty.

Special mention should be made of the servants. They all got life into their parts. Biondello and Gremio deserving most credit for keeping the audience amused.

All in all the Barnard girls proved that Shakespeare was right when he said that Shakespeare was right when he said that about everybody being a natural horn actor, but they also called attention to the fact that he said nothing about stage managers. When the curtain rose on Act IV, all Barnard gasped at the sight of a brand new woodland "drop." and they gasped some more when the treetops descended plumb in the middle of a tender love scene between Lucentio and Bianca. There was more trouble for poor Lucento later on, when--well, wouldn't Kyrle Bellew himself be disturbed if he were telling the heroine all about her ruby lips and sparkling eyes, if just at that moment a 'rubberneck' wagon passed and the man with the horn drowned out the soft music by yelling: 'Barnard on your left!' in the very best part of the speech?

Otherwise things went smoothly except that the guests at the banquet scene were so busy remembering their lines that they all sat around and forgot to eat.

Here is the cast:
Baptista, a rich gentieman of Padau[sic]... H. Fox
Vincentio, an old gentleman of Pisa... O. Rilke
Lucentio, son to Vincentio, in love with Bianca... J Goldberg
Petruchio, a gentleman of Verona... F. S. Wyeth

A Tailor ... M. Eggleston
Servants to Petruchio
Nathaniel ... (A. Requa
Gregory ... (P. Johnson
Philip ... (O. Ibiseng
Sugarsop... (M. Oberndorfer
A Cook.... (A. Muller
-- Daughters to Baptista

Bianca ... (Jessie Cochran

Servants ... N. Hamburger, H. Scheuer, A. Rothenberg, E. Plaut
Pages... F. Read, M. Bailey
Wedding Guests--Misses Wells, Stewart, Alexander, Finch, Heiden, M. Hirsch, D. Dietrich. M. Budds, L. Schoedler, F. Sammet, R. Salmowitz and F. McLane.

Besides the two performances of yesterday there will be another afternoon and evening performance today.

Much of the success of the play is attributed to Gertrude Stein, chairman of the committee, and her assistants, Adelaide Requa, Eva vom Baur, Florence Wyeth, Grace Reeder and Katherine Gay. The coaching was done by Alfred Young and Miss Florence Gerrish.

Prominent among the patronesses were Mrs. Nicholas Murray Butler, Mrs. Joseph F. Choate, Mrs. Franz Boaz, Mrs. Seth Low and her Excellancy[sic] Kang Mue Wah."

San Antonio Express - October 21, 1923

RIVERA RETURNS TO MEXICO

Special Correspondent to the Express.
SAN LUIS POTOSI, Mexico, Oct., 20 - Liberado Rivera, the agitator and companion of Ricardo Flores Magon, who has been released from the penitentiary at Ft. Leavenworth, Kans., with the understanding that he immediately abandon the United States, has telegraphed relatives here that he will come to San Luis Potosi to locate. Rivera fled from Mexico uring President Diaz's reign but returned for a time during the recent revolution and again left in 1915.

buckeye616: Thank you for the information about Rivera's first name. Some newspapers (New York Times) cite him as Librado, while others (San Francisco Chronicle, San Antonio Express) use the first name of Liberado. We will include both variants in the record when we update the database.

Thanks for sharing this image, I was able to add it to the Wikipedia pages for both of these men
