This is the last rendering that I could find, so I've run out of storyboard and ad comps to post. This particular layout was for a magazine ad, I don't recall the client, ad agency or art director. It was a large 12 x 18" rendering done using markers on layout paper.
Below is an example of how I develop a page layout for an automotive catalog.
I first make a very rough color sketch which is often shown to the art director to see if I am on target.
If the sketch is approved, I the do a comprehensive layout which is put together with all of the other pages as a catalog. This then is presented to the agency's client for approval.
The comp layout is used by the artists and photographers as a guide for the art and photography.
If your are interested in seeing more comp layouts and storyboard work pick up a copy of my book Advertising Layout Techniques. I wrote this book in 1983 and it was published by Watson Guptill Publications. You can find used copies on the internet.
