Girls’ Colorful Pop Art Birthday Party Square Sticker

A vibrant pop art style invitation design featuring a large pink speech bubble prominently placed in the center against a white background. The speech bubble has a glossy, cartoon-like appearance with a bold black outline and small circular highlights, ready to contain party details or messages. Surrounding the central bubble, colorful pop art elements burst with energy including comic book-style "POW!" and "BOOM!" text effects, rainbow starbursts, polka dot patterns, and lightning bolt shapes in bright primary colors of red, blue, yellow, and green. The overall design captures the playful, high-energy aesthetic of 1960s pop art with bold outlines, Ben-Day dot patterns, and a cheerful color palette perfect for a children's celebration.
