But that factor aside, the characteristics of successful stamps and posters are quite similar. They both depend on a dominant visual to attract attention, and both need to impart their messages quickly. There's considerable latitude with posters, but with postage stamps these requirements must be met precisely. A stamp design is basically an illustration with a little type. At a minimum, it must contain the initials USA and the numerals of the denomination.
Most stamps also contain the name of the person or subject portrayed.
Stamp designers generally do a creditable job of getting these elements to cooperate in a pleasing arrangement. The exceptions are rare instances when the illustrator or designer appears not to have planned for the type. A brief look back will put the situation in perspective. The traditional stamp design is a classical portrait in an ornate frame. In 1948 a political favor resulted in a stamp honoring the American poultry industry.
