Linda and Jerry Gonto thrive on the real thing when it comes to mid-century modern design: the pristine creative spawn of designers like Eames, Bertoia and Saarinen, preferably arranged in a classic MCM abode, like the one they bought when they moved here from Detroit a couple of years ago. The couple developed their taste in design during years of vintage retailing in the Midwest; in Denver, they're sharing their knowledge with the community at Retro House Love, a smartly appointed temple to mid-mod on the south end of Old South Pearl Street that opened last May. In the market for Mad Men barware or a really cool '50s-era lamp? Better get some Retro House Love.
