The European media is reporting that two works by Bolivian artist Gastón Ugalde were burned in The Netherlands by customs officials who considered their content an illicit substance. Ugalde's works, intended for a group exhibition by 8 artists that opened on June 9th, were made using coca leaves. They were retained by customs authorities and later incinerated. Gastón Ugalde sent his works last December 15th to be included in a group show curated by artist Scarlett Hooft Graafland, after a request by the Central Bank of the Netherlands. Months later, the exhibition organizers were summoned in front of a judge, because the material used in the work's manufacturing is classified as an illicit substance. As soon as the artist was informed of the retention of his work, appeals began to the authorities in The Netherlands, in a tribunal in Amsterdam, to clarify "the relevance of the technique for the exhibition, since these were works of art and samples of my work, which was accepted after a hearing; however, when they went looking for the material, they realized it had been burned after some time in the warehouse", said the Ugalde. Faced with these facts, the renowned Bolivian artist sent two different works to The Netherlands to replace the lost ones in the show; if these are not allowed in, the organizers will exhibit the legal documents detailing the proceedings in order to inform audiences about the incident.
