Mauro Oliveira was born in São Paulo, Brazil and raised on the outskirts under extreme poverty, with no running water or electricity. He and his six siblings were sent to a military state-run orphanage after both parents passed away in their 30s. His passion for the United States and art started at age nine in the orphanage. His first art project, at age 10, was to paint and decorate the plain tin piggy banks that were given out for free by the banks and then selling them. Oliveira encouraged and supervised the other children to do the same and raised funds for food. He did stay out of trouble, studied hard and surmounted every obstacle on his way, dreaming of making it to America one day. He made it to college with straight A’s and won a student exchange program contest sponsored by the Federal University of Uberlândia, Brazil. He studied journalism and the arts and immigrated to the U.S. in 1990.

Oliveira has worked in several different art media, from oil pastels and charcoal sketches to clay sculptures. His greatest influences are Pablo Picasso and the Spanish artist Joan Miró. Oliveira's artworks have been exhibited throughout the U.S. as well as internationally, most recently in Hong Kong, Los Angeles and New York.

The first decades of the 20th century were a period of artistic upheaval, with modern art movements including Cubism, Surrealism, Futurism and Dadaism questioning centuries of traditional views of what art should be. Using abstraction, experimental forms and interdisciplinary techniques, painters, sculptors, photographers, printmakers and performance artists all pushed the boundaries of creative expression.

Major exhibitions, like the 1913 Armory Show in New York City — also known as the “International Exhibition of Modern Art,” in which works like the radically angular Nude Descending a Staircase by Marcel Duchamp caused a sensation — challenged the perspective of viewers and critics and heralded the arrival of modern art in the United States. But the movement’s revolutionary spirit took shape in the 19th century.

The Industrial Revolution, which ushered in new technology and cultural conditions across the world, transformed art from something mostly commissioned by the wealthy or the church to work that responded to personal experiences. The Impressionist style emerged in 1860s France with artists like Claude Monet, Paul Cézanne and Edgar Degas quickly painting works that captured moments of light and urban life. Around the same time in England, the Pre-Raphaelites, like Edward Burne-Jones and Dante Gabriel Rossetti, borrowed from late medieval and early Renaissance art to imbue their art with symbolism and modern ideas of beauty.

Emerging from this disruption of the artistic status quo, modern art went further in rejecting conventions and embracing innovation. The bold legacy of leading modern artists Georges Braque, Pablo Picasso, Frida Kahlo, Salvador Dalí, Henri Matisse, Joan Miró, Marc Chagall, Piet Mondrian and many others continues to inform visual culture today.

Mixed media is a type of art that sees artists using a range of materials or more than one medium. Find a range of mixed media paintings and other artworks for your space today on 1stDibs.

Mixed media is distinct from multimedia, which describes art involving electronic media, including video, computers and digital elements. Artists combine painting, drawing, photography and sculpture for mixed media art. Instead of sticking to one form, they aim to break boundaries and create unique pieces. Pop art is one of the vibrant periods for mixed media art, with Jasper Johns and Robert Rauschenberg among its most fabled producers. Rauschenberg, like many mixed media artists, used found objects in his work, from cast-off furniture to newspapers.

Collage is one of the most well-known areas of mixed media. Artists use various types of paper, fabric, photographs and more to create one cohesive work. A type of collage is assemblage, which involves 3D objects.

While artists may use fabric in collage, it can be the very substance of the art itself. Fabric art makes extensive use of texture. Artists may paint or embroider on fabric to create layers of texture and color to evoke a specific feeling. They can also transfer photos onto fabric for innovative ways to display visuals.

Resin-based art has clean, sharp lines and a definitive shape. Resin is a liquid that hardens to a high-gloss surface and is used to seal wood, counters and floors. Resin can also seal artwork, and many artists tint it using pigment powder, ink, spray paint and other vivid materials. If water is added, the resin will turn milky instead of being completely transparent. It’s common for artists working in mixed media to use resin on nontraditional surfaces like glass, wood, metal and stone. This creates a shine that’s perfect to brighten a dull space in the home or office.
