I take it as a given that the work of Peter Max isn’t everybody’s cup of tea, but I’ve always been a fan. When I was a kid, this nifty green coffee pot was a fixture in my family’s kitchen, and what can I say, that insidious infiltration of my psyche must have left some residue, because I usually find that Max’s colorful, playful psychedelia has the effect of raising my spirits. I like his stuff. I learned recently that Max published a book of paper airplanes in 1971 for Pyramid Books. What a marvelous idea! The cover of the book features a plea to treat the environment with care, and Max’s infectious positivity makes its way into the design of the planes, which are emblazoned with cute messages like “HA HA” or “I’M A BIRD” or “I CAN’T TALK, ‘CAUSE I’M LAUGHING.” The book sold for $1.50 at the time. If you want to try making these at home, obviously a good color printer will help, but the used editions of the books are surprisingly affordable.
