Guardanapo De Papel Colorful Retro Robots Boy Birthday Party

A whimsical illustration of a circular border made up of cartoon robots arranged in a perfect circle. The robots are drawn in a retro-futuristic style with square heads and various mechanical details. The robots are colored in blue, green, yellow, and red tones, each with different eye designs - some with single red eyes, others with blue eyes, and some with simple black windows. The robots have different mechanical appendages including antennae, jointed arms and legs, and various mechanical parts and bolts. The robots are drawn with a hand-drawn quality with visible line work and shading. The illustration has a clean white background and is arranged in a perfect circular pattern with equal spacing between each robot. The robots are positioned facing inward toward a central white space in the center of the circle. The overall style is playful and child-friendly with a vintage aesthetic.
