Bold patriotic screen-print illustration featuring a powerful muscular horse rendered in dynamic side-profile stance as the central foreground subject, positioned in front of a stylized American flag that fills the upper background as a structured graphic element with clean bold stripes in deep crimson red and off-white and a canton of navy blue packed with crisp white five-pointed stars arranged in rows. The horse is illustrated in a heroic silhouette style with confident linework, coat rendered in warm chestnut brown with bright white highlights tracing the muscle contours, mane and tail flowing with motion suggesting strength and freedom. Beneath the horse, arched in a proud banner curve, the text "4TH OF JULY" set in wide slab serif all-caps lettering with thick white fill, deep navy blue drop shadow offset downward, and a bold red outer stroke giving it a stamped patriotic authority. Stars accent each side of the text as decorative spacers. The flag stripes are simplified into clean flat graphic bands rather than photographic fabric, keeping the whole composition screen-print friendly with no more than six ink colors. Illustration technique is bold clean vector-inspired linework with flat ink fills and subtle halftone dot shading on the horse musculature for vintage poster depth. Print finish is crisp and graphic with light vintage ink grain across the entire design giving it a worn Independence Day poster character. Ink palette of deep navy blue, crimson red, warm chestnut brown, bright white, and golden yellow accent. All set against one flat solid dark navy blue background. | PODspy AI Design
