Who made a 1987 issue of design quarterly magazine for the walker art center in minneapolis

April Greiman was the graphic designer who made a 1987 issue of Design Quarterly magazine for the Walker Art Center in Minneapolis. 
She is a famous designer celebrated as one of the first artists to use computer technology as a design tool, which is obvious in that issue of the magazine. Her work is a classic example of postmodernism, the artistic era we live in today, where artists tend to make extravagant and unorthodox art.
