Illustration and Graphic Design are thought of as two separate disciplines. This can be the case. They are two separate job descriptions. However, in many important ways the two over-lap. Not only in the document, newspaper, catalog or web site that they appear in but in the purpose that they serve.
And that purpose is simple: relay information is a structured way.
In catalogs, art falls on top of photography with sizes, prices or shipping information. On a website, borders, shadows and artwork shape the borders that photography appears in. It is a technique that is used so much that it is almost invisible.
What about examples of these techniques in another era? We should be able to spot the transitions and archiac techniques much more quickly there.
Ferdinando Ongania's Early Venetian Printing Illustrated, the book above, was originally published in 1895 but covers Italian Renaissance prints and illustration work from roughly 1400 to 1600. Here, there there are is an incredible integration of graphic design (text and textual elements) and illustration.
Since there is no photography, the balance is achieved by placement of elements with a structural similarity. The text seems illustrated and the illustrations contain text.
We can see this harmony at work but without the slick gradients, shading layers and glossy styles that are commonplace today. The important thing to remember is that these Classic era designers had the exact same purpose that Designers and Illustrators have today, and no mutually exclusive job titles.
