This image was commissioned by 'Business Week' magazine to be used in a limited edition book of 3000, published in 1963 by McGraw-Hill to illustrate its "Business America" series. The publication was titled "WOODCUTS of Fifteen American Cities From the Business Week Collection." It promoted "Business / New Patron of the Arts" with a forward noting business patronage over the years and noted "From 1960-1962 Business Week commissioned fourteen prominent woodcut artists to illustrate its 'Business America' series."
Casarella created three color blockprints using his paper relief method (technically not all 'woodcut') for the series, one for Denver and the other two for Detroit (this image was not selected for the book).
"Detroit" is a loose depiction of an automobile assembly line and was meant as a tribute to the city of Detroit - the "Free Wheeling City of Brains and Brawn. Detroit...The Motor Capital. Birthplace of mass production. Home of the transportation titans who have put America on wheels."
