If you have and important, familiar or national work of art, it must be placed away from sunlight or any other artificial source of light, since the colors in paintings like watercolor tend to fade away and the canvas may crack and loosen.
The first contributions from Henri Pitter and Paul Biolley on Costa Rican insects appeared between 1892 and 1897, while working for the National Geographic Institute. They sent the samples to United States and Europe. Mister José Fidel Tristán and Biolley increased the collecting work and specimen determination.
