Marcelo Barbero
He was a student of the famous Santos Hernández from Madrid. After Santos died, he finished guitars for the widow for a few years that Santos had started to build under a separate label and also built new guitars for the widow in his style. Later, he started his own business and built his own models successfully until the middle of the 50s. He is considered one of the most gifted guitar builders of his epoch. I owned a few of his instruments from the 40s and 50s, and they were the showpieces of my collection.
