Different products require different design or illustrative techniques to communicate the message the seller wants to convey to the perspective buyer. This communication of ideas or message needs to be clear, whether it be a promotional poster, a cd cover or insert, a product package, a book cover or a magazine cover. Patricia Browne believes that a well designed and/or illustrated packaging or promotional piece conveys not only an image but implies an emotion or impression of that product, person or organization it represents. The examples above are actual products in use or some were done as samples or concept work made for the client or perspective clients.
