In 2007, as part of the celebrationsfor 20 years of exceptional work in Uruguay, hehadfive successful art exhibits. His art work inaugurated the new Carnival Museum in February and then he was asked by the U.S. Embassy to do a one man show for President Bushes' recent visit to Uruguay. He alsoparticipated in a collective artexhibit, celebratingPunta del Estes' 100th birthdayat theMantra Casino Hotel. Fripur, Uruguay's leading fishing company, asked him to do a one man art exhibitat theMontevideo's Sheraton Hotel. More recently,at the Uruguayan Presidential Executive Office: "Libertad" Palace, he did a one man show, honoringthe twenty most popular Uruguayan writers, illustrating their short tales works for children. The exhibit consisted of one watercolor illustration framed with a fragment of either a legend or a short story about Uruguay. Themain goal of this project was to bring back to light those forgotten writers that almostevery Uruguayan adult read in their childhood. Themethodology illustrates thetaleswith a watercolor painting and this made the audience more involved in the reading process, mixing two arts. The exhibit was for all age groups, but it was mainly focused on children. The exhibit was visited by many schools with the purpose of promotingreading and art appreciation.That main goal was certainly achieved.
