When Dana and Melanie Harvey got married, they bought a 1950 Buick to drive to Las Vegas that lacked one important safety feature: seatbelts. After installing new ones himself, Dana made his wife a handbag from the leftover material that, to him, seemed only practical ("A seatbelt is inherently stain-resistant and heat-resistant," he explains.) Although you can now find seat-belt handbags at kiosks all over the country, Harvey's is the original outlet, and we've got one right here on Melrose. Not content simply to develop their own product technology, the entreprising couple recently sponsored Open Canvas, a nationwide art contest that gives up-and-coming designers a chance to host an installation on the store's prime real-estate. This Friday, the public will have the opportunity to see the competing work, meet the judges (including Tarina Tarantino and Paul Frank) and partake in free bar snacks and beer at Harvey's "open art" party. There will be blank canvases set up for anyone who wants to do a little public demonstration of their own, and enough raw seatbelt material on hand to strap in the nation's crash-test dummies. Tomorrow night from 7pm-11pm at 7955 Melrose Ave., Los Angeles 90036.
