Optical art, known as Op art, can make an eye-popping addition to your collection. The works of Victor Vasarely exemplify the drawings, paintings, and sculpture done in this style, which produces visually challenging works that often use optical illusions. The Hungarian artist started producing his graphic op art works in the 1930s, and Vasarely was recognized as a leader of the movement. Vasarely's abstract "Zebra," which depicts two entwined animals composed entirely of black and white streaming stripes, is a widely recognized iconic op art work. He also created more genuinely abstract serigraphs in the cubist and op art styles, and fans can still find Vasarely signed art prints, serigraphs, and lithographs, even though the artist passed away in 1997. You can use a Victor Vasarely print or series of prints, with "moving" geometric shapes in bright primary and secondary colors, to decorate the walls of a lively kids' play room or your family's rec room. Teens who are into psychedelic and intense artworks might like a framed Vasarely print among their graphic art posters. The works, both original and reproductions, are mainly done in large square sizes, but you can find smaller prints too. Fans of op art can find a range of Vasarely works when they choose from the vast inventory available on eBay.
