If you were a part of this era, but especially if you weren’t, you must see Graphic Means.
These days, it is easier to find information regarding printing in 15th century Europe than graphic design processes in the United States during the 1970s and ’80s. The latter, the focus of Graphic Means, was a major transition for the design and printing industry as centuries old procedures and machinery made way for photographic processes and eventually digital technology. This dramatic shift has not been well-documented, perhaps due to the quick speed of the conversion or that it is still in recent memory.
