A letterhead is a printed heading on the top of a sheet of paper that typically includes the name, logo, and contact information of a business or individual. It serves as a professional way to present correspondence and helps to establish brand identity. Letterheads are commonly used for official documents, letters, and invoices. In addition to providing essential information, letterheads can enhance the overall appearance of written communication. They often feature design elements such as colors, fonts, and graphics that reflect the style of the business or organization. This makes letterheads an important tool for effective branding and communication.
