These reworked advertisements were at first left alone, lasting for up to several months, but as KAWS’ popularity grew, the ads became increasingly sought after. In addition to New York, KAWS has done work in Paris, London, Berlin, and Tokyo. In the late 90s, KAWS began to design and produce limited edition vinyl toys, "an instant hit with the global art toy-collecting community," especially in Japan, where this genre is well respected and widespread. More toys and later clothing were made for Original Fake, a recent collaborative store with Medicom Toy, in the Aoyama district of Tokyo where an original limited edition product is released each week. KAWS has also participated in other commercial collaborations with Nigo for A Bathing Ape, Jun “Jonio” Takahashi for Undercover, snowboard projects with Burton, and sneakers with Nike and Vans. His most recent collaboration was with Comme des Garçons. KAWS’ acrylic paintings and sculpture have many repeating images, all meant to be universally understood, surpassing languages and cultures.
One of KAWS' early series, Package Paintings, was made in 2000. This series, entitled The Kimpsons, subverted the famous American cartoon, The Simpsons. KAWS explains that he "found it weird how infused a cartoon could become in people's lives; the impact it could have, compared to regular politics." also, KAWS has reworked other familiar icons such as Mickey Mouse, the Michelin Man, and the Smurfs. KAWS has successfully blurred the line between fine art and mass-produced merchandise. He uses his products to allow his imagery to reach a larger audience than that of the fine art world. The artist is currently an member in both the commercial and fine art communities. Recent solo exhibitions include OriginalFake at the Bape Gallery in Tokyo (2003) and Tokyo First at Parco Gallery in Tokyo (2001). KAWS has been periodically showing both paintings and products at Colette in Paris since 1999. His work is included in the traveling exhibition Beautiful Losers, which started at the Cincinnati Contemporary Art Center and will be traveling through 2009 throughout the US and Europe.
