About the article "Portrait of Dr. Gachet", section "Etching".

Candidate passages:
Van Gogh, introduced to etching by Gachet, made the etching "Portrait of Doctor Gachet" in 1890.
Gachet and Van Gogh discussed creating a series of southern France themes but that never happened.
This was the one and only etching, also known as "L'homme à la pipe" (Man with a pipe), that Van Gogh ever made.
Van Gogh's brother, Theo, who received an impression of the etching, called it "a true painter's etching.
No refinement in the execution, but a drawing on metal."
It is a different pose than that in Van Gogh's "Portrait of Dr. Gachet", owned by Musée d'Orsay.
The National Gallery of Canada finds that "The undulating flow of the line is typical of the expressive quality of Van Gogh's late style."
The impression owned by the National Gallery is from one of the 60 printings following Van Gogh's death by Dr. Gachet's son, Paul Gachet Jr. Gachet's collector's stamp appears on the bottom edge of the print.
Dr. Paul Gachet lived in Auvers-sur-Oise.
He was acquainted with the avant-garde artists of the time.
Through this connection, Vincent van Gogh moved to Auvers to be treated by him, though he considered the doctor to be in a worse state than himself.
Gachet befriended Van Gogh and was the subject of two portraits, one of which, "Portrait of Dr. Gachet", was sold at auction for over $80m (£48m) in 1990.
Van Gogh died by a gunshot to the chest.
The room on the upper floor of the Auberge Ravoux where he died has been preserved, although no furniture remains.
Auvers-sur-Oise is the final resting place of both Vincent and his brother Theo van Gogh, who died six months later.
In Vincent van Gogh's birthplace Zundert (NL), the street next to the small Protestant church where his father preached, has been renamed "Auvers-sur-oise-straat" (straat(NL)=street(EN)=rue(FR)). 
The Gachet Family.
"Portrait of Dr. Gachet" is one of the most revered paintings by Dutch artist Vincent van Gogh of Dr. Paul Gachet, who took care of him in his last months.
In 1990, it fetched a record price of $82.5 million ($75 million, plus a 10 percent buyer's commission).
Gachet was also an artist of the Impressionist era.
He was an amateur painter and engraver.
Vincent van Gogh went to the doctor for medical care.
Van Gogh saw himself in the doctor; like himself, he saw in Dr. Gachet “the heart-broken expression of our time.” Similar to many of van Gogh’s portraits, the painting is a study not of the physical features of the man, but of the inner qualities of the doctor’s personality.
The portrait of Dr. Gachet notes all the tiniest details of his appearance and depicts them in the way that van Gogh sees them.
The characteristics of the doctor’s image are all freely painted so that the viewer may see them the same way that van Gogh does. 
Portrait of Dr. Gachet is one of the most revered paintings by the Dutch artist Vincent van Gogh.
It depicts Dr. Paul Gachet who took care of Van Gogh during the final months of his life.
There are two authenticated versions of the portrait, both painted in June 1890 at Auvers.
Both show Doctor Gachet sitting at a table and leaning his head on his right arm but they are easily differentiated in color and style.
In 1990, the first version fetched a record price of $82.5 million ($75 million, plus a 10 percent buyer's commission) when sold at auction in New York.
When accounting for inflation, this is still the highest price paid for art at a public auction. 
There is a second version of the portrait which was owned by Gachet himself.
In the early 1950s, along with the remainder of his personal collection of Post-Impressionist paintings, it was bequeathed to the Republic of France by his heirs.
The authenticity of the second version has often come under scrutiny due to a number of factors.
In a letter dated 3 June 1890 to Theo, Vincent mentions his work on the portrait, which includes "...a yellow book and a foxglove plant with purple flowers."
The subsequent letter sent to Wilhelmina also mentions "yellow novels and a foxglove flower."
As the yellow novels are absent from the second version of the painting, the letters clearly reference only the original version.
Gachet, as well as his son, also named Paul, were amateur artists themselves.
Along with original works, they often made copies of the Post-Impressionist paintings in the elder Gachet's collection, which included not only works by Van Gogh, but Cézanne, Monet, Renoir and others.
These copies were self-declared, and signed under the pseudonyms Paul and Louis Van Ryssel, yet the practice has thrown the entire Gachet collection into question, including the doctor's portrait.
Additionally, some critics have noted the sheer number of works to emerge from Van Gogh's stay in Auvers, roughly eighty in seventy days, and questioned whether he painted them all himself.
Partly in response to these accusations, the Musée d'Orsay, which holds the second version of the Gachet portrait as well as the other works originally owned by the doctor, held an exhibit in 1999 of his former collection.
In addition to the paintings by Van Gogh and the other Post-Impressionist masters, the exhibition was accompanied by works of the elder and younger Gachet.
Prior to the exhibition, the museum commissioned infrared, ultraviolet and chemical analysis of eight works each by Van Gogh, Cézanne, and the Gachets for comparison.
The studies showed pigments on the Van Gogh paintings faded differently than the Gachet copies.
It also emerged that the Gachet paintings were drawn with outlines and filled with paint, whereas the Van Gogh and Cézanne works were painted directly to canvas.
Van Gogh also used the same rough canvas for all his paintings at Auvers, with the exception of "The Church at Auvers" (whose authenticity has never been questioned).
In addition to scientific evidence, defenders claim that while the second version of the "Portrait of Dr. Gachet" is often considered to be of lesser-quality than many of Van Gogh's works in Arles, it is superior in technique to anything painted by either the elder or younger Gachet.
Dutch scholar J.B. de la Faille, who compiled the first exhaustive catalog of Van Gogh works in 1928, noted in his manuscript, "We consider this painting a very weak replica of the preceding one, missing the piercing look (of the original)."
Editors of the posthumous 1970 edition of Faille's book disagreed with his assessment, stating they considered both works to be of high quality.
