Colourful Dump Trucks 4th. Birthday Party Invitation

A decorative border frame illustration featuring four dump trucks arranged in a square pattern. Each truck has a different colour: yellow at the top left, blue at the top right, green at the bottom left, and red at the bottom right. The trucks are rendered in a simple, childlike style with large wheels, basic cabin designs, and open dump bodies. Green leafy branches frame the corners of the image - two branches with large oval leaves on the sides and a smaller branch with leaves at the top. The branches have a natural, organic feel with visible leaf veins and shadows. The entire illustration is set against a white background. The trucks are positioned at equal distances from each other, creating a balanced composition. The illustration has a whimsical, nursery or children's book style with clean lines and soft colours.
