Sought-after original color 23″ x 35″ advertising poster for the Apple II computer featuring the colorful 'rainbow' logo at center, with stylized black text below: "Apple ][, the home/personal computer." Displayed behind glass and in fine condition. Manock recalls that these posters were used for the April 1977 West Coast Computer Fair in San Francisco where the Apple II was debuted, and believes that he got this example at the Fair. From the collection of product design engineer Jerrold C. Manock, and accompanied by a letter of provenance signed by Manock.
