Phil Torrone from Adafruit writes, “A million internet years ago in 2008 when I was Senior Editor at MAKE Magazine, Ladyada and I went to DC Comics to meet the MAD Magazine folks for a collaboration issue with MAKE and MAD, it was the Spy vs Spy issue, volume 16 cover by Sam Viviano. Spy vs. Spy is a wordless black and white comic strip that has been published in Mad magazine since 1961. It was created by Antonio Prohias, a Cuban national who fled to the United States in 1960 days before Fidel Castro took over the Cuban free press.”
I visited the same year, as it happens, and even took photos of many of the same things!
