guttojugg1, To create a 1960s-style poster for a hamburger joint with a man wearing glasses as the central figure, you can draw inspiration from the work of graphic artists of that era, such as Milton Glaser. Milton Glaser was famous for his iconic "I ♥ NY" design and other influential works in the 1960s.Incorporate bright, bold colors, playful typography, and a distinct retro aesthetic that was characteristic of advertising during the 1960s. Use pastel tones and bold outlines to give the poster that nostalgic, vintage look.
