Birthday party poster, a large-sized banner or poster designed for a party or event. Party posters include images, colors, text, and graphics that highlight the party's theme or topic.

A party poster can be used to invite guests to the event, emphasize the party theme, and reflect the party atmosphere. For example, for a birthday party, a party poster featuring a picture of the birthday child or a favorite cartoon character or superhero can be used. For New Year's parties, a party poster featuring New Year symbols, fiery champagne glasses, and bright lights can be used.

Party posters are usually printed in large sizes and displayed at the party venue. To attract people's interest in the party and create the atmosphere, they can also be displayed in public areas near the party venue. Party posters are a great tool to capture the attention of those attending the party and add a special touch to the party.
