This was a two color poster that employed two split fountains on the press in order to create the effect of a full color announcement. Of course, this requires a sympathetic pressman and willingness to spend a lot of time adjusting the results. - Milton Glaser
Milton Glaser (b. 1929- 2020) Easily considered one of the godfathers of American classic design and poster art, Glaser was one of the founders of Push Pin Studios along with Seymour Chwast. Glaser also co-founded New York Magazine in 1968 and went on to create his own famously well regarded studio. Over the course of his career he has created many beloved posters incorporating a myriad of styles and techniques, such as his psychedelic Bob Dylan image. His most iconic contribution may be the 'I love New York' logo, with a red heart replacing the word love. Milton Glaser partnered with Poster House on many occasions, most recently including the #CombatCovidPSACampaign before his death.
