This design features a festive birthday greeting. At the center of the image, there is a banner with the words "Happy Birthday" written in elegant cursive script. The banner is adorned with a string of black triangular flags, each bearing the word "Happy" in white. The background is a stark white, which contrasts with the black banner and flags, making the text stand out. Adding a touch of celebration, a black balloon with a string is attached to the bottom of the banner. The overall design is simple yet celebratory, conveying a warm birthday wish.
