TINWORK SANTA HOT AIR BALLOON MEXICO folk ART

I have this great piece hanging in my special room. At least I think it's great :) I found it at the thrift store. It is made of all tin and is from Oaxaco Mexico. Beautiful bright colors, and depicts santa holding the Oaxaca Mexico colored flag. I love everything about it. Was made as a christmas decoration.Today, the city of San Miguel de Allende is the center for tinwork production in Mexico. Artisans make everything from lanterns to nichos to decorative mirrors to Christmas decorations like this painted Santa. The only reference I have is from the Artifacts at The Children's Museum of Indianapolis. This is the only place I have been able to locate any info.
Any other info would be so apprecited.Thanks for looking!
