Ken Garland is generally regarded as a key figure in the development of Graphic Design since the 1960s so I figure that his work fits like a glove in a brief entitled, "What is Graphic Design?"
Here are a couple of his designs I like a lot:
'Keniston Housing Associates Brochure'

This is a quality piece of design in my opinion. The colours work extremely well together and the different typeface for each letter gives the design character and edge. Revolutionary for something from the 1985-1987 years. Here are the other typographical ideas Garland had in support of the design:
'Keniston Type Variants'

'1970 Metrication Board Annual Report Cover'

Garland states on his website that the above design was to be designed so that with each future annual report the cover could be changed simply by changing the colour and the title. This is a successful design in meeting those demands in my opinion. Also, the general hard edged, precise, vertical and horizontal lines communicate the general notion of what the metrication board actually do well.
'University of Reading - Ken Garland - A Word in Your Eye'

This design works for me due to the simple double meaning with words actually being in the eye on the design. Double meaning is something that I personally love to see in designs. The subtle blues are aesthetically pleasing too.
And that's a bit of Ken Garland!
