Its rarity is evidenced by the fact that it does not appear to have been been published in any publicly available print medium to date, nor anywhere else previously online.
However, a proof print of it has lain dormant in the extensive Wilde holdings of the Harry Ransom Center, The University of Texas at Austin—in the James McNeill Whistler collection to be precise—and their copy might be the only extant print.
To see how this photograph re-emerged and how it affects the total count of known Sarony images of Oscar Wilde, let’s start the ball rolling.
There is a pleasing symmetry in the idea of the flamboyant Napoleon Sarony photographing Oscar Wilde because they were both specialists in posing—albeit from opposing perspectives. So it is not surprising that they also had parallel views about it.
It is pleasing to see that recent Wilde studies continue to highlight the emergent nature of Oscar’s American experience, during which time he nurtured the art of public speaking, conducted his first press interviews, staged his first play, had his iconic photographs taken, and stockpiled—to use an American word—material for his future epigrams and works.
But there is a crucial American beginning for Oscar that has been under-appreciated: I refer to his first brush with literary society. It occurred during an event at 149 Fifth Avenue in New York City, the then home of an organisation of journalists known as the Lotos Club.
Eating oysters in Connecticut is a big thing; and when in Hartford, CT, there was only one place to go: Honiss’ Oyster House. In 1981 the New York Times ran an article about the famous old place, now long since gone:
It isn’t every restaurant in Connecticut that can claim – as the Honiss Oyster House Company does – to have served Mark Twain, Babe Ruth, Andre Previn and Steve Martin, or to have the very booth where Buffalo Bill Cody ate regularly when he was in town with his Wild West Show.
Honiss’s dimly-lit basement walls are crammed with photographs of customers past. There are more than a thousand pictures in all, dating to the 1880’s, when Thomas Honiss and Fred Atchinson purchased the then-40-year-old restaurant downstairs in the United States Hotel.
What the newspaper did not mention, and possibly because the restaurant also failed to realize it, is that Oscar Wilde also partook of Honiss’ famous oysters while residing at the United States Hotel in 1882.
After traveling across the vast expanses of the American south for more than a month, lecturing in 18 cities, Wilde returned to New York for some rest and relaxation with friends at the exclusive Summer resorts of the north-east.
On July 15, 1882. Oscar gave a courtesy lecture at the Casino during a week’s stay with Julia Ward Howe and friends at Newport, RI, (revisited here) and he did not lecture again for two and a half weeks.
During that time he:
— visited Long Beach with Sam Ward where he was to be found creating interest on the beach;
—cruised around Long Island for three days with Robert Roosevelt aboard his yacht, occasionally swimming, fishing and calling in at popular hotels;
—visited the actress Clara Morris at her retreat in Riverdale, NY;
—stayed with statesman John Bigelow at his summer home at Highland Falls, near West Point;
—vacationed at Long Branch spending a night as guest of former President of the United States, General Ulysses S. Grant, which must have provided a interesting counterpoint to his recent stay with Jefferson Davis, the former president of the Confederate States of America, at his home at Beauvoir;
—traveled to Peekskill to stay with clergyman and social reformer Henry Ward Beecher with whom he attended a church service and a military band concert.
After all that urbane socializing it was time to head for the hills for more urbane socializing—and a return to lecturing.
The social lion was about to become a mountain lion in The Catskills.
In verifying Oscar Wilde’s 1882 lecture tour of North America, it was prudent to begin with the four published itineraries by Mikhail, Ellmann, Page, and Beckson. 
Unfortunately, none of these chronologies agrees with any other, and each is either incomplete or wrong in various respects—so it has been necessary to make numerous additions and corrections to dates, locations and lecture titles. 
It is a pleasing break to the routine when one discovers something new, such as a previously unrecorded event. Or, rarer still, a previously unknown lecture, as was the case with the redefining of Wilde’s final stop of the tour in New York on November 27, 1882.
Now another new lecture has emerged: it is an appearance by Wilde at Narragansett Pier.
