Seymour Chwast shaped the evolution of graphic design and illustration, designing innovative designs that gained international recognition for his playful expressive approach to type and illustrative layout. His unique designs in illustrations began a new design wave, based on revivalism (a radical alternative to the Swiss formalism of that time). Chwast's colourful and witty designs have been used on packaging, children and adult books, magazines, advertisements and 100’s of posters that displays a captivating sense of humour next to a strong understanding of traditional design methods.
Chwast's passion for the historical design movement has reintroduced the knowledge, appreciation and reapplication of past styles and forms. The 1970's Chwast designs drew extensively on the 19th century illustrations as seen in posters for the sensational Houdini poster in 1973 along. In 1971 he worked together with Phyllis la Farge to produce the book “The Pancake King”. He also frequently worked in woodcut and monoprint, using thick bold outlines as seen in "End Bad Breath poster from 1976.
Chwast’s creative style that had a distinct influence on contemporary visual communications was later hired by McDonalds to design the packaging for their new product line of Happy meals.
Along with Chwast many different contributions to graphic design, his co-founders for his company Pushpin Studios, Milton Glaser and Edward Sorel together designed their own line of candies. Presenting a whimsical, cheeky style of candies. Mints in the shape of caviar, almonds as pearl candies, lavishly proportioned chocolate bars and martini flavoured candy olives, producing creative designs for packaging for each.
