The vibrant artwork depicting elements of the Mexican Day of the Dead celebration appears to be painted by the Mexican folk artist Sandy Garcia.
 
Garcia is renowned for her expressive paintings that draw inspiration from traditional Day of the Dead imagery and symbolism while incorporating her own unique, contemporary style. The central subject shows a striking portrait figure donning celebratory attire like the large red hat emblazoned with "Calavera" and decorated with skulls and skeletons. The exaggerated facial features convey a sense of sorrow amidst the joyous occasion.
 
The artist masterfully blends indigenous Mexican cultural motifs such as skulls and floral designs with bold colors and stylized techniques, evolving the iconic Day of the Dead artistic traditions into a modern folk art aesthetic. The work captures the celebratory spirit and complex emotions surrounding death and remembrance that define this rich cultural observance.
