Imagine having photos of your life’s accomplishments enlarged to life size and posted all around a major city’s main square — a free, outdoor exhibit for all to see.

Hard to imagine, isn’t it?

Well, for my old friend from New York, the world-famous street art photographer Martha (“Marty”) Cooper, who turned 76 last month, this sort of honor has become almost unexceptional.

Right now, and for at least the next two months, there is a breathtaking exhibition of four decades of Marty’s work – documenting the ever-expanding graffiti and street art scene all around the world – on the outside fences surrounding the beautiful, vast Parque Alameda, in the city’s historic centro, in Querétero, Mexico.

A total of 101 of Marty’s most iconic photographs, dating from 1978, were enlarged to roughly 5 ft. square and mounted on weather-resistant vinyl for everyone to enjoy.

This project, titled “Evolution of a Revolution by Martha Cooper,” was the brainchild of Edgar Sanchez of PaxUrbana in Querétero, who also produced the outdoor installation “El Agua es Una” (Water is One) last year at Querétero’s Cultural Center (CECEQ).

(Please scroll down to “Search the Archives” to see my post, “Martha Cooper: Rock Star in the Realm of Street Art,” published last April 16, for my full story on this event and more on my friendship with Marty.)

As Edgar wrote in the introduction to this new endeavor, “This exhibition shows the explosive energy of the legendary Martha Cooper, known globally as the godmother of graffiti. … With this exhibition we want to reveal to Querétero and its graffiti writers the brilliant place that Mexican talent has achieved in the world.”

I was able to visit Marty, as well as Edgar and his partner Sigre from Estonia, plus  photographer Jaime Rojo from Brooklyn Street Art, last week in Querétero and see the magnificent exhibition first-hand. Marty had been, as ever, at far-flung street-art events in recent weeks, including India and Haiti, and was on her way to Spain following these few days in Mexico.

“I can’t keep up with you,” I told her.

“Sometimes I can’t keep up with myself,” she confessed to me.

At one point, Edgar took us to a “surprise” that local street artists were painting in Marty’s honor: a city-block-long wall, outside of a grammar school, painted to resemble an old New York City subway car, the kind Marty documented in her first book, considered the international graffiti writers’ bible, Subway Art (Thames and Hudson, 1984).

Although she may be old enough to be these young Mexican street artists’ abuela (grandmother), they all unabashedly adore her, as all street artists do all over the world, no doubt because, with her devotion to this art form as expressed in her photography, she preserves their ephemeral artwork for posterity. She also shares it on Instagram with her hundreds of thousands of followers. She is their queen, and she basks in their love. It’s a beautiful thing to see.
