Liniers is related to viceroy Santiago de Liniers. He began drawing from a very early age; he has remarked that he began to draw in order to enjoy movies at home. "I wanted to have Star Wars and the only way to have it was to draw it. So we could look at it whenever we wanted to." His father was a lawyer and his mother worked at various jobs, including making slippers and little paintings. He has two siblings, who are younger, and is married and has three daughters.
Career
In regards to the name he uses for his comic strips, Liniers has remarked: "Liniers is my second name. In Buenos Aires there was a viceroy named Liniers, who ended up being executed by firing squad. He was my ancestor, something like a greatgreatgreatgrandfather. So when I began to sign my comic strips, I used the name, because I like names that do not entirely and exactly are appropriate to the subject –for example, the teddy bear in my comic strip is called Madariaga." He studied advertising, but ultimately decided to pursue a career in comics. His work is influenced by Patrick McDonnell, Hergé, Goscinny and Uderzo, Quino, Héctor Germán Oesterheld and Francisco Solano López, Charles Schulz and George Herriman. He started working in fanzines, then moved on to magazines and newspapers. His work has been featured in Lugares, ¡Suélteme!, Hecho en Buenos Aires, Calles, Zona de Obras, Consecuencias y ¡Qué suerte!, Olho Mágico, 9-11 Artists respond, and Comix 2000. Along with Santiago Rial Ungaro, Liniers published Warhol para principiantes, for Ediciones Era Naciente in 2001. Liniers appeared as a presenter at the second Pecha Kucha night in Buenos Aires, October 3, 2006. In September 1999 he started publishing a weekly strip called Bonjour in NO!, a supplement of Página/12. Bonjour is very experimental and features some adult language, and showcases many characters that would reappear in later works. Bonjour appeared for the last time on June 27, 2002. In June 2002, fellow cartoonist Maitena got him into the Argentine newspaper La Nación, where he began a new daily strip called Macanudo, which appears on the last page of the paper. Just like Bonjour, Macanudo is very experimental and deals with meta humor. Conejo de viaje is a collection of illustrated travel journals that describe his journeys through France, Portugal, Germany, Spain, Argentina, and Antarctica. The Big Wet Balloon, a TOON Book is the first book by Liniers published in the U.S. In 2014 the artist illustrated some covers for The New Yorker
