Most originals left are on canvas. The few left that are under glass are either from the period 1987 - 2001, and they are painted with gouache.
OR they are from my time in Wisconsin, 2002 - 2011, and they are painted with acrylics on paper. Most works created in Texas, 2012 - 2018, were painted on paper using acrylics. The time in Mexico is a different thing altogether, as here I have only sold two originals during seven years. As a comparison, while I lived in Wisconsin and Texas, I sold about 30 originals at each location. In Mexico, I have sold NADA.
While art is available at arts and craft shows everywhere in the USA, Mexico doesn't have ANY of that. The only arts and crafts sold on markets in Mexico are Mexican heritage-inspired. Other art, like the one I create, for example, is only available at high-end galleries in Mexico City, San Miguel de Allende, and Monterrey
