Guzman Clowns

I too have a collection of Guzman Clowns from Colombia, SA. They are exceptional. I have never seen any of this artist's work except at a small art gallery that used to exist in San Juan, Puerto Rico. I would like to learn more about these clowns. I do not intend to sell mine, but I would certainly be interested in purchasing others. They were not expensive when I purchased them, but they are very appealing.
